merge: integrate claude/read-repo-YMu21 branch

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).

+## Support
+
+Silent Send is a weekend project — built because the developer wanted it and could not find what the developer wanted (reveal especially). No donations needed. If you find it useful, great — enjoy. If it helps you keep your personally identifiable information private, that's thanks enough. More people having access to privacy is the goal.
+
+That said, Claude access isn't free. If you have a desire to give a coffee back, it would be appreciated — but don't feel any obligation to tip.
+
+**[Buy me a coffee on Ko-fi](https://ko-fi.com/YOUR_KOFI_USERNAME)**
+
+A few things to know:
+- Donations do not influence updates. Silent Send may or may not get updates based on the developer's usage and available time.
+- Donating does not create any warranty, support obligation, or expectation of future development.
+- This is and always will be a free, non-commercial project.
