-// Package updatemanager provides automatic update management for the NetBird client.
-// It monitors for new versions, handles update triggers from management server directives,
-// and orchestrates the download and installation of client updates.
-//
-// # Overview
-//
-// The update manager operates as a background service that continuously monitors for
-// available updates and automatically initiates the update process when conditions are met.
-// It integrates with the installer package to perform the actual installation.
-//
-// # Update Flow
-//
-// The complete update process follows these steps:
-//
-//  1. Manager receives update directive via SetVersion() or detects new version
-//  2. Manager validates update should proceed (version comparison, rate limiting)
-//  3. Manager publishes "updating" event to status recorder
-//  4. Manager persists UpdateState to track update attempt
-//  5. Manager downloads installer file (.msi or .exe) to temporary directory
-//  6. Manager triggers installation via installer.RunInstallation()
-//  7. Installer package handles the actual installation process
-//  8. On next startup, CheckUpdateSuccess() verifies update completion
-//  9. Manager publishes success/failure event to status recorder
-//  10. Manager cleans up UpdateState
-//
-// # State Management
-//
-// Update state is persisted across restarts to track update attempts:
-//
-//   - PreUpdateVersion: Version before update attempt
-//   - TargetVersion: Version attempting to update to
-//
-// This enables verification of successful updates and appropriate user notification
-// after the client restarts with the new version.

-// Package installer provides functionality for managing NetBird application
-// updates and installations across Windows, macOS. It handles
-// the complete update lifecycle including artifact download, cryptographic verification,
-// installation execution, process management, and result reporting.
-//
-// # Architecture
-//
-// The installer package uses a two-process architecture to enable self-updates:
-//
-//  1. Service Process: The main NetBird daemon process that initiates updates
-//  2. Updater Process: A detached child process that performs the actual installation
-//
-// This separation is critical because:
-//   - The service binary cannot update itself while running
-//   - The installer (EXE/MSI/PKG) will terminate the service during installation
-//   - The updater process survives service termination and restarts it after installation
-//   - Results can be communicated back to the service after it restarts
-//
-// # Update Flow
-//
-// Service Process (RunInstallation):
-//
-//  1. Validates target version format (semver)
-//  2. Determines installer type (EXE, MSI, PKG, or Homebrew)
-//  3. Downloads installer file from GitHub releases (if applicable)
-//  4. Verifies installer signature using reposign package (cryptographic verification in service process before
-//     launching updater)
-//  5. Copies service binary to tempDir as "updater" (or "updater.exe" on Windows)
-//  6. Launches updater process with detached mode:
-//     - --temp-dir: Temporary directory path
-//     - --service-dir: Service installation directory
-//     - --installer-file: Path to downloaded installer (if applicable)
-//     - --dry-run: Optional flag to test without actually installing
-//  7. Service process continues running (will be terminated by installer later)
-//  8. Service can watch for result.json using ResultHandler.Watch() to detect completion
-//
-// Updater Process (Setup):
-//
-//  1. Receives parameters from service via command-line arguments
-//  2. Runs installer with appropriate silent/quiet flags:
-//     - Windows EXE: installer.exe /S
-//     - Windows MSI: msiexec.exe /i installer.msi /quiet /qn /l*v msi.log
-//     - macOS PKG: installer -pkg installer.pkg -target /
-//     - macOS Homebrew: brew upgrade netbirdio/tap/netbird
-//  3. Installer terminates daemon and UI processes
-//  4. Installer replaces binaries with new version
-//  5. Updater waits for installer to complete
-//  6. Updater restarts daemon:
-//     - Windows: netbird.exe service start
-//     - macOS/Linux: netbird service start
-//  7. Updater restarts UI:
-//     - Windows: Launches netbird-ui.exe as active console user using CreateProcessAsUser
-//     - macOS: Uses launchctl asuser to launch NetBird.app for console user
-//     - Linux: Not implemented (UI typically auto-starts)
-//  8. Updater writes result.json with success/error status
-//  9. Updater process exits
-//
-// # Result Communication
-//
-// The ResultHandler (result.go) manages communication between updater and service:
-//
-// Result Structure:
-//
-//	type Result struct {
-//	    Success    bool      // true if installation succeeded
-//	    Error      string    // error message if Success is false
-//	    ExecutedAt time.Time // when installation completed
-//	}
-//
-// Result files are automatically cleaned up after being read.
-//
-// # File Locations
-//
-// Temporary Directory (platform-specific):
-//
-// Windows:
-//   - Path: %ProgramData%\Netbird\tmp-install
-//   - Example: C:\ProgramData\Netbird\tmp-install
-//
-// macOS:
-//   - Path: /var/lib/netbird/tmp-install
-//   - Requires root permissions
-//
-// Files created during installation:
-//
-//		tmp-install/
-//	   installer.log
-//		  updater[.exe]                    # Copy of service binary
-//		  netbird_installer_*.[exe|msi|pkg] # Downloaded installer
-//		  result.json                       # Installation result
-//		  msi.log                           # MSI verbose log (Windows MSI only)
-//
-// # API Reference
-//
-// # Cleanup
-//
-// CleanUpInstallerFiles() removes temporary files after successful installation:
-//   - Downloaded installer files (*.exe, *.msi, *.pkg)
-//   - Updater binary copy
-//   - Does NOT remove result.json (cleaned by ResultHandler after read)
-//   - Does NOT remove msi.log (kept for debugging)
-//
-// # Dry-Run Mode
-//
-// Dry-run mode allows testing the update process without actually installing:
-//
-// Enable via environment variable:
-//
-//	export NB_AUTO_UPDATE_DRY_RUN=true
-//	netbird service install-update 0.29.0

-// Package reposign implements a cryptographic signing and verification system
-// for NetBird software update artifacts. It provides a hierarchical key
-// management system with support for key rotation, revocation, and secure
-// artifact distribution.
-//
-// # Architecture
-//
-// The package uses a two-tier key hierarchy:
-//
-//   - Root Keys: Long-lived keys that sign artifact keys. These are embedded
-//     in the client binary and establish the root of trust. Root keys should
-//     be kept offline and highly secured.
-//
-//   - Artifact Keys: Short-lived keys that sign release artifacts (binaries,
-//     packages, etc.). These are rotated regularly and can be revoked if
-//     compromised. Artifact keys are signed by root keys and distributed via
-//     a public repository.
-//
-// This separation allows for operational flexibility: artifact keys can be
-// rotated frequently without requiring client updates, while root keys remain
-// stable and embedded in the software.
-//
-// # Cryptographic Primitives
-//
-// The package uses strong, modern cryptographic algorithms:
-//   - Ed25519: Fast, secure digital signatures (no timing attacks)
-//   - BLAKE2s-256: Fast cryptographic hash for artifacts
-//   - SHA-256: Key ID generation
-//   - JSON: Structured key and signature serialization
-//   - PEM: Standard key encoding format
-//
-// # Security Features
-//
-// Timestamp Binding:
-//   - All signatures include cryptographically-bound timestamps
-//   - Prevents replay attacks and enforces signature freshness
-//   - Clock skew tolerance: 5 minutes
-//
-// Key Expiration:
-//   - All keys have expiration times
-//   - Expired keys are automatically rejected
-//   - Signing with an expired key fails immediately
-//
-// Key Revocation:
-//   - Compromised keys can be revoked via a signed revocation list
-//   - Revocation list is checked during artifact validation
-//   - Revoked keys are filtered out before artifact verification
-//
-// # File Structure
-//
-// The package expects the following file layout in the key repository:
-//
-//	signrepo/
-//	  artifact-key-pub.pem      # Bundle of artifact public keys
-//	  artifact-key-pub.pem.sig  # Root signature of the bundle
-//	  revocation-list.json      # List of revoked key IDs
-//	  revocation-list.json.sig  # Root signature of revocation list
-//
-// And in the artifacts repository:
-//
-//	releases/
-//	  v0.28.0/
-//	    netbird-linux-amd64
-//	    netbird-linux-amd64.sig   # Artifact signature
-//	    netbird-darwin-amd64
-//	    netbird-darwin-amd64.sig
-//	    ...
-//
-// # Embedded Root Keys
-//
-// Root public keys are embedded in the client binary at compile time:
-//   - Production keys: certs/ directory
-//   - Development keys: certsdev/ directory
-//
-// The build tag determines which keys are embedded:
-//   - Production builds: //go:build !devartifactsign
-//   - Development builds: //go:build devartifactsign
-//
-// This ensures that development artifacts cannot be verified using production
-// keys and vice versa.
-//
-// # Key Rotation Strategies
-//
-// Root Key Rotation:
-//
-// Root keys can be rotated without breaking existing clients by leveraging
-// the multi-key verification system. The loadEmbeddedPublicKeys function
-// reads ALL files from the certs/ directory and accepts signatures from ANY
-// of the embedded root keys.
-//
-// To rotate root keys:
-//
-//  1. Generate a new root key pair:
-//     newRootKey, privPEM, pubPEM, err := GenerateRootKey(10 * 365 * 24 * time.Hour)
-//
-//  2. Add the new public key to the certs/ directory as a new file:
-//     certs/
-//     root-pub-2024.pem    # Old key (keep this!)
-//     root-pub-2025.pem    # New key (add this)
-//
-//  3. Build new client versions with both keys embedded. The verification
-//     will accept signatures from either key.
-//
-//  4. Start signing new artifact keys with the new root key. Old clients
-//     with only the old root key will reject these, but new clients with
-//     both keys will accept them.
-//
-// Each file in certs/ can contain a single key or a bundle of keys (multiple
-// PEM blocks). The system will parse all keys from all files and use them
-// for verification. This provides maximum flexibility for key management.
-//
-// Important: Never remove all old root keys at once. Always maintain at least
-// one overlapping key between releases to ensure smooth transitions.
-//
-// Artifact Key Rotation:
-//
-// Artifact keys should be rotated regularly (e.g., every 90 days) using the
-// bundling mechanism. The BundleArtifactKeys function allows multiple artifact
-// keys to be bundled together in a single signed package, and ValidateArtifact
-// will accept signatures from ANY key in the bundle.
-//
-// To rotate artifact keys smoothly:
-//
-//  1. Generate a new artifact key while keeping the old one:
-//     newKey, newPrivPEM, newPubPEM, newSig, err := GenerateArtifactKey(rootKey, 90 * 24 * time.Hour)
-//     // Keep oldPubPEM and oldKey available
-//
-//  2. Create a bundle containing both old and new public keys
-//
-//  3. Upload the bundle and its signature to the key repository:
-//     signrepo/artifact-key-pub.pem      # Contains both keys
-//     signrepo/artifact-key-pub.pem.sig  # Root signature
-//
-//  4. Start signing new releases with the NEW key, but keep the bundle
-//     unchanged. Clients will download the bundle (containing both keys)
-//     and accept signatures from either key.
-//
-// Key bundle validation workflow:
-//  1. Client downloads artifact-key-pub.pem and artifact-key-pub.pem.sig
-//  2. ValidateArtifactKeys verifies the bundle signature with ANY embedded root key
-//  3. ValidateArtifactKeys parses all public keys from the bundle
-//  4. ValidateArtifactKeys filters out expired or revoked keys
-//  5. When verifying an artifact, ValidateArtifact tries each key until one succeeds
-//
-// This multi-key acceptance model enables overlapping validity periods and
-// smooth transitions without client update requirements.
-//
-// # Best Practices
-//
-// Root Key Management:
-//   - Generate root keys offline on an air-gapped machine
-//   - Store root private keys in hardware security modules (HSM) if possible
-//   - Use separate root keys for production and development
-//   - Rotate root keys infrequently (e.g., every 5-10 years)
-//   - Plan for root key rotation: embed multiple root public keys
-//
-// Artifact Key Management:
-//   - Rotate artifact keys regularly (e.g., every 90 days)
-//   - Use separate artifact keys for different release channels if needed
-//   - Revoke keys immediately upon suspected compromise
-//   - Bundle multiple artifact keys to enable smooth rotation
-//
-// Signing Process:
-//   - Sign artifacts in a secure CI/CD environment
-//   - Never commit private keys to version control
-//   - Use environment variables or secret management for keys
-//   - Verify signatures immediately after signing
-//
-// Distribution:
-//   - Serve keys and revocation lists from a reliable CDN
-//   - Use HTTPS for all key and artifact downloads
-//   - Monitor download failures and signature verification failures
-//   - Keep revocation list up to date
