Kai (Tam Nhu) TranandGitHub e055dac199 feat(cliproxy): add account safety guards to prevent Google account bans (#516)
* feat(cliproxy): add account safety guards to prevent Google account bans

Implements cross-provider isolation to prevent Google from flagging
concurrent OAuth usage across different client IDs (ref: #509, #512).

Three pillars:
1. Auto-pause enforcement at session launch — conflicting accounts in
   other Google OAuth providers are paused so CLIProxyAPI can't use them,
   restored on session exit with crash recovery via auto-paused.json
2. Ban/disable detection — error responses matching Google ban patterns
   auto-pause the affected account to prevent further damage
3. Cross-provider conflict warnings during OAuth registration

Key design decisions:
- PID-based session tracking for crash recovery (dead PID = restore)
- Timestamp comparison prevents restoring ban-paused accounts on exit
- Schema validation on auto-paused.json prevents corrupted state
- Falls back to warn-only when another session is managing isolation

* fix(cliproxy): address code review feedback (attempt 1/5)

- Re-read auto-paused.json before write in enforceProviderIsolation to
  reduce concurrent write race window
- Use actual email from registry for display instead of raw accountId
- Export maskEmail for testability
- Add 27 unit tests covering ban detection, email masking,
  cross-provider duplicate detection, enforcement lifecycle,
  crash recovery, and timestamp-guarded restore

* fix(cliproxy): address remaining review feedback (attempt 2/5)

- Add handleBanDetection test verifying account pause on ban error
- Add warnCrossProviderDuplicates tests (true/false/non-Google)
- Document PID reuse limitation in isPidAlive JSDoc comment
