📄 Description

Avoid compiling regexes on every anonymization call by promoting them to package-level compiled variables.

This reduces per-call CPU and allocation overhead in log/string anonymization paths.

Describe your changes

Moved regex patterns in client/anonymize/anonymize.go to package-level compiled variables:
- domainKeyRegex
- ipv4Regex
- ipv6Regex
- schemeURIRegex
Removed per-call regexp.MustCompile(...) inside:
AnonymizeString
AnonymizeSchemeURI
Kept anonymization behavior unchanged while reducing repeated regex compile work in hot log/string paths.
Verified with:
- go test ./client/anonymize
