Use cwd-based detection instead of env-aware detection for gt hook status
display. This ensures we show the hook for the agent whose directory you're
in, not the agent from GT_ROLE env var.
Before: cd ~/gt/beads/crew/dave && gt hook → showed gastown/crew/joe (wrong)
After: cd ~/gt/beads/crew/dave && gt hook → shows beads/crew/dave (correct)
