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).

-// Package wisp provides hook file support for Gas Town agents.
+// Package wisp provides utilities for working with the .beads directory.
 //
-// DEPRECATED: Hook files are deprecated in favor of pinned beads.
-// Work is now tracked via beads with status=pinned and assignee=agent,
-// which can be discovered via query rather than explicit file management.
-//
-// Commands like `gt hook`, `gt sling`, `gt handoff` now use:
-//
-//	bd update <bead> --status=pinned --assignee=<agent>
-//
-// On session start, agents query for pinned beads rather than reading hook files.
-// This follows Gas Town's "discovery over explicit state" principle.
-//
-// The hook file functions are kept for backward compatibility but are deprecated.
-// Old hook files:
-//   - hook-<agent>.json files tracked what bead was assigned to an agent
-//   - Created by `gt hook`, `gt sling`, `gt handoff`
-//   - Read on session start to restore work context
-//   - Burned after pickup
+// This package was originally for "hook files" but those are now deprecated
+// in favor of pinned beads. The remaining utilities help with directory
+// management for the beads system.
