feat: commandcode usage query via /alpha endpoints with Provider API key (v0.5.0)

- New config commandcode_api_key (user_... provider key, long-lived);
  when set, usage queries hit /alpha/billing/credits + /alpha/usage/summary
  with Bearer auth — no more 7-day session cookie rotation
- session_token kept as optional fallback (legacy /internal + cookie path)
- alpha credits lack opensourceMonthlyCredits; formatter tolerates
- alpha non-200 passes through status without echoing upstream body
