- Add cortex/tools/scratch.py with scratch_read/write/append/clear tools
- Register all four scratch tools in the orchestrator tool registry
- Create inara/SCRATCH.md as the backing file (never distilled/archived)
- Fix auth.py: expiresAt reflects short-lived access token (~8h) not the
1-year refresh token — suppress expiry warning when refreshToken is present
