fix(statusline): filter in_progress beads by identity in getCurrentWork

The getCurrentWork function was returning ANY in_progress bead from the
workspace rather than only beads assigned to the current agent. This caused
crew workers to see wisps assigned to polecats in their status bar.

Changes:
- Add identity parameter to getCurrentWork function
- Add identity guard (return empty if identity is empty)
- Filter by Assignee in the beads query

This complements the earlier getHookedWork fix and ensures both hooked
AND in_progress beads are filtered by the agent's identity.

Fixes gt-zxnr (additional fix).
