Workflow: add push trigger for main branch on json/*.json and update the "Get JSON file for script" step to handle both workflow_dispatch and push events. The step now collects changed json/*.json files, validates each has a .slug with jq, ignores metadata/update-apps.json/versions.json, writes changed_app_jsons.txt, and sets a count output for downstream steps.
Installer & ct scripts: normalize indentation/formatting, ensure aliases.json and plugin-settings.json are initialized as {} and repos.json as [] when missing, and add missing trailing newlines. These changes improve robustness and shellcheck friendliness and make the workflow respond to direct pushes of app JSON files.
Introduce degoog support: add ct/degoog.sh (container orchestration and update handler), install/degoog-install.sh (in-container install using Bun, deploy prebuilt release, create systemd service on port 4444) and json/degoog.json (app metadata and default resources). ct script includes update routine with backups, Bun install, and fetch_and_deploy_gh_release usage. Also update documentation: refine contribution guide (CONTRIBUTING.md) with fork/testing workflow, templates, and metadata guidance; expand misc README to reflect canonical misc/* function library responsibilities and references.
