feat(kugetsu): add KUGETSU_VERBOSITY for PM agent output control

Add KUGETSU_VERBOSITY environment variable with three modes:
- total (default): Work silently, post only final summary
- verbose: Post every action (current noisy behavior)
- hybrid: Post only on errors

Export KUGETSU_VERBOSITY in cmd_delegate so PM agent can read it.

Also includes KUGETSU_TEMP_DIR export from #92 fix.

Fixes #46
