feat(hermes): modernize hermes agent adapter and skills support

- Add --yolo and --accept-hooks headless auto-approval flags to spawn_spec and resume_spec
- Define Hermes TUI input delimiters (input_prompt='❯', input_rule_pattern='─{10,}')
- Refactor verify_artifact and discover in hermes.py using session started_at timestamps
- Fix HERDR_EPOCH capture timing before spawn in create_session.sh to prevent epoch race
- Update reconcile.sh for hermes drift-C multi-candidate and sibling claimed exclusion
- Add Hermes contract, epoch filtering, and C-ambiguous unit tests (140 passed)
- Add agent evaluation report and final review reports for Hermes support
