The SessionHookCheck was incorrectly flagging 'gt prime --hook' as invalid,
only accepting 'session-start.sh' wrapper. The --hook flag properly handles
session_id passthrough via stdin JSON, making it a valid alternative.
Changes:
- Update usesSessionStartScript to accept --hook flag
- Add containsFlag helper to prevent false positives (e.g., --hookup)
- Update error messages and fix hints to suggest both options
- Add comprehensive tests including edge cases
Tests cover:
- Bare gt prime (fails)
- gt prime --hook (passes)
- gt prime --hookup (fails - not a valid flag)
- gt prime --verbose --hook (passes - flag order doesn't matter)
- session-start.sh (passes)
- Mixed valid/invalid hooks in same file
- Town-level and rig-level settings
