patch

Fix Kimi usage endpoint returning 404 when Moonshot API endpoint path format changed. Add fallback from /v1/coding-plan/usage (hyphen) to /v1/coding_plan/usage (underscore) when the first endpoint returns 404 url.not_found. Auth errors (401/403) still short-circuit immediately without fallback.
