Adopt the live ChatGPT usage API (found via github.com/rygel/AIUsageTracker, MIT)
so Codex % is fresh every poll instead of only as fresh as the last local
rollout write:
GET https://chatgpt.com/backend-api/wham/usage
Authorization: Bearer <access_token from $CODEX_HOME/auth.json tokens>
ChatGPT-Account-Id: <account_id>
-> rate_limit.primary_window / secondary_window {used_percent, reset_at}, plan_type
poll() now tries the live endpoint first and falls back to the rollout snapshot
when the token is missing/expired/offline (we read the current OAuth token but
don't refresh it). Live-first fixes the staleness of the rollout-only approach:
verified live s=1% (5h, resets 300m), w=0% (7d, resets 10080m), st="Plus" — a full
fresh window vs the old stale past-reset heuristic.
+4 tests (live preferred, limit_reached->limited, 401->rollout fallback, no-auth
->rollout). 126 passed, 2 Linux-only failures (baseline).

OpenAICodexProvider replaces the openai stub. It reads the rate-limit snapshot
the Codex CLI already records locally (no second auth): each turn Codex writes a
token_count event into $CODEX_HOME/sessions/**/rollout-*.jsonl whose
payload.rate_limits mirrors Claude's model — primary (5h) + secondary (weekly),
each with used_percent + resets_at + plan_type. The provider surfaces the
freshest such snapshot; a window whose reset time has passed is reported as a
fresh 0% (local read, so current in-session and self-heals between sessions).
primary -> s/sr, secondary -> w/wr, plan_type -> status ("Plus"/…),
rate_limit_reached_type -> "limited". No per-token cost (subscription), so the
two rate-limit bars are the metric, per the locked v3 decision.
Verified against the real ~/.codex: full daemon payload with openai active =
{pv:openai, pnm:"OpenAI Codex", ac:0x10a37f, st:"Plus", ok:true, weekly reset}.
registry test updated (openai now real, zai still stub); +7 provider tests.
113 passed, 2 Linux-only failures (baseline). spec: hiddenimport added.
