Add phaseguard flag for supervisor questions to wait indefinitely (#4)

* Add phaseguard flag to supervisor ask command

When phaseguard is enabled (--phaseguard flag), the supervisor's ask
command will block indefinitely waiting for user response instead of
timing out after the default 1 hour. This ensures that phase transitions
requiring user confirmation cannot proceed without explicit approval.

Changes:
- Add phaseguard field to AskQuestionRequest in server handler
- Add phaseguard field to AskQuestionRequest in API client
- Add --phaseguard CLI flag to AskArgs
- Update supervisor_ask() to accept phaseguard parameter
- Modify ask_question handler to skip timeout check when phaseguard=true
