Eradicate hook files, use pinned beads only (gt-rgd9x)

- Remove hook functions from internal/wisp/io.go (WriteSlungWork, ReadHook, BurnHook, etc.)
- Remove hook types from internal/wisp/types.go (SlungWork, Wisp, etc.)
- Update up.go to query pinned beads instead of reading hook files
- Remove SlungWork field from molecule_status.go
- Remove hook-*.json pattern from .beads/.gitignore
- Delete live hook file /Users/stevey/gt/deacon/.beads/hook-deacon.json

Work is now tracked exclusively via pinned beads (status=pinned, assignee=agent).
