feat(cli): add 'hf agent status' wrapper for POST /calendar/agent/status

The plan-schedule workflow needs to report agent runtime status
(idle/busy/on_call/exhausted/offline) at the end of planning, but the
cli had no wrapper for this — workflows were dropping inline curl in
the middle of their procedure to hit the backend.

This adds 'hf agent status --set <status> [--reason ...] [--recovery-at ...]'.
The endpoint identifies the agent purely from X-Agent-ID + X-Claw-Identifier
headers (no token), so the cli reads AGENT_ID from env and falls back
to hostname() for CLAW_IDENTIFIER if it isn't set — same convention
the openclaw plugin uses. Refuses to send if AGENT_ID env is missing,
since this only makes sense from a pcexec/agent runtime context.

Surface entry added so 'hf --help' lists it.
