Codex 631fee9254 fix(openclaw): harden B3 evidence trust and path boundaries
- Add _reject_symlink_chain() protection against ancestor symlink escapes
- Implement dirfd-based atomic writes with O_DIRECTORY | O_NOFOLLOW
- Add mandatory --trust-policy parameter with strict validation
- Integrate SSH signature verification via ssh-keygen -Y verify
- Authority field hard fail (present: false or missing -> BLOCKED)
- Self-audit rejection (reviewer != executor/capture/credential)
- Update template with trust_policy_key field
- Update README with trust policy and dirfd documentation
- Update task file with B3 BLOCKED_EVIDENCE_REQUIRED status

Codex 9577613497 fix(openclaw): harden B3 evidence trust and path boundaries
Complete security hardening for B3 evidence collection tool:

Security fixes:
1. Ancestor symlink path escape prevention - reject_symlink_chain()
2. Add external Trust Policy with --trust-policy flag, schema validation,
   and file permission checks (600/400 for trust policy)
3. Authority present: false or missing now hard-fails (was soft-fail)
4. Self-review rejection - reviewer must differ from capture/credential
5. SSH signature verification with ssh-keygen -Y verify
6. SFTP trust policy delivery verification
7. Reject_Float nan/infinity in JSON parsing
8. JSON key duplication detection
9. Dirfd atomic writes with O_DIRECTORY|O_NOFOLLOW parent fd

Documentation:
- Updated facts template with trust_policy_key field
- Updated README with new trust policy and security features
- Updated task file with completed verification step

Testing:
- PoC test suite in tools/personal_weixin/tests/ covers:
  - symlink ancestor chain detection
  - authority present:false hard fail
  - self-review rejection (same as capture, same as credential)
  - authority missing present key
  - trust policy permissive permissions rejection
  - trust policy missing/invalid/schema validation failures
