merge: integrate claude/read-repo-YMu21 branch

Browse Source 
Merged changes from the other session:
- Ko-fi support link in options footer
- PPI → PII renaming across codebase
- Legal/licensing updates (stronger disclaimer, non-commercial only)
- Custom secret/auto-redact patterns
- Internal refactoring of secret scanner to auto-redact naming
- Custom domains in popup Options tab
- Additional AI services (Perplexity, DeepSeek, HuggingChat, Poe)
- Developer sites (GitHub, GitLab, Reddit, StackOverflow, Pastebin)
- Dynamic content script registration for custom domains

Resolved conflicts in options.html and popup.html (kept newer
"Auto Redact" naming with custom patterns description).
