feat: Add 'hooked' status for GUPP work assignment (bd-s00m)

Separates semantics of 'pinned' (identity records) from work-on-hook:
- 'pinned' = domain table / identity record (agents, roles) - non-blocking
- 'hooked' = work on agent's hook (GUPP-driven) - blocks dependents

Changes:
- Add StatusHooked constant to types.go
- Update all blocking queries to include 'hooked' status
- Add cyan styling for 'hooked' in UI output
- Create migration 032 to convert pinned work items to hooked
