GET /usage serves the numbers behind Claude Code's /usage, read with the
CLI's own stored OAuth credentials (nothing to configure). The endpoint
is undocumented, so parsing is defensive -- the generic limits[] array
becomes labeled window bars, unknown kinds surface under their raw name,
and any failure degrades to an 'unavailable' snapshot with the reason.
One UsageProvider per paid service behind a caching monitor that
enforces the >=180s minimum poll regardless of phone refreshes; no
background polling at all. ureq (rustls) does the outbound call, with
the process-level CryptoProvider now chosen explicitly in main -- ureq
brings ring while axum-server brings aws-lc-rs, and with both in the
graph rustls refuses to guess.
App: a Usage screen off the session list -- per-window bars colored by
utilization with relative reset times. Verified live: 74%/26%/16%
windows rendered against the real endpoint.
