Jason 22d2872c33 feat(logging): persist diagnostics across restarts and redact secrets ...

Backend half of the logging overhaul.

Retention:
- Keep the last 4 rotated files at 20MB each and stop deleting logs on
  startup, so a crash's prior-run logs survive a restart.
- Apply the persisted log level right after plugin registration instead
  of at the end of setup.
- Bound crash.log with size-based rotation (5MB x 2).

Secret redaction on every log path:
- Proxy: strip userinfo/query from upstream URLs (keep path for
  diagnostics), exact-match redact known auth.api_key/access_token,
  classify request/response bodies instead of logging them, header
  allowlist.
- Redact the Gemini `?key=` in cache-trace endpoints.
- Omit MCP custom-field values (headers may carry tokens).
- Redact deeplink and model-fetch URLs before logging.

Docs:
- FAQ points users to the persistent crash.log for support workflows.
