Root cause: tmux statusline showed wrong hook for all java crewmembers
because GT_CREW env var wasn't set in tmux session environment.
Changes:
- statusline.go: Add early return in getHookedWork() when identity is empty
to prevent returning ALL hooked beads regardless of assignee
- crew_at.go: Call SetEnvironment in the restart path so sessions created
before GT_CREW was being set get it on restart
Fixes gt-zxnr.
