// Characterization of the services/usage.ts opencode split (god-file decomposition): the
// OpenCode / OpenCode Zen triple-window fetcher (getOpencodeUsage) moved into
// services/usage/opencode.ts so usage.ts stays a thin dispatcher. Behavior-preserving move —
// this locks the export surface and the no-key fail-open message; the window-shaping edges are
// exercised via fetchOpencodeQuota stubs in opencode-quota-fetcher tests.
