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
fix(quota): declare monthlyTargetTime (undeclared since v0.4.2 refactor), ReferenceError when Command Code data absent; add undeclared-identifier scan to pagecheck (v0.4.5)

   - 请求优先走宿主提供的 `host.http.do` 回调（复用宿主代理、日志与鉴权管道），离线或未注入宿主时自动无缝降级至 Go 标准 `net/http`。
   - 全面解析 `credits`（月度基础额度、开源奖励额度、总可用额度）与 `windowLimits`（5小时短期滑动窗口、周度窗口限额，计算已用量、上限、剩余量、使用百分比及重置时间）。
 5. **嵌入式纯单文件 QuotaCard 资源页**：
   - 页面挂载于 `/v0/resource/plugins/commandcode/quota`。
   - 零外部 CDN 依赖，纯内置 HTML + CSS + JS，深色/浅色模式自适应。
   - 具有进度条颜色变化、5小时/周限额卡片、秒级动态重置倒计时、同源 `localStorage` 鉴权与一键刷新。
+   - Tab 切换：Command Code / OpenCode Go / All（`#opencode` / `#all` hash 记忆状态）。

+   - 上游接口：`GET https://opencode.ai/zen/go/v1/usage`，`Authorization: Bearer` 认证（同样走 `host.http.do` 优先 + `net/http` 兜底）。
+   - 解析 rolling（5h）/ weekly / monthly 三个窗口的 `status`/`percent`/`resetsAt`，容忍未知 status 值。
+   - 聚合端点 `/plugins/commandcode/all` 一次返回两个 provider，部分失败不拖死另一 provider。

Author	SHA1	Message	Date
yuez	d7733552ee	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	2026-09-23 17:13:01 +08:00
yuez	c2b8d89ba6	fix(quota): declare monthlyTargetTime (undeclared since v0.4.2 refactor), ReferenceError when Command Code data absent; add undeclared-identifier scan to pagecheck (v0.4.5)	2026-09-23 10:09:23 +08:00
yuez	9d1884cf20	feat(quota): All tab Command Code card shows Plan + 5h/weekly/monthly windows with reset times (v0.4.4)	2026-09-20 15:25:29 +08:00
yuez	447ce65c9b	feat(quota): All tab first in tab bar; remove header usage-alert badge (v0.4.3) - Tab order: All \| Command Code \| OpenCode Go (All remains the default) - Drop the global status badge in the header action row and its updateGlobalBadge aggregation; per-card chips and All-tab provider badges are unaffected	2026-09-20 14:52:24 +08:00
yuez	4fdc9ad6c8	feat(quota): All as default tab with per-key OpenCode cards grouped by provider, bump v0.4.2	2026-09-20 14:20:01 +08:00
yuez	2f1b2fb821	build: pagecheck as standalone node script (inline escaping was fragile)	2026-09-20 13:18:21 +08:00
yuez	3097d96a8e	chore: bump v0.4.1 to force plugin re-sync with fixed page (v0.4.0 asset shipped with broken JS)	2026-09-20 13:00:35 +08:00
yuez	0a9213ec38	fix(quota): remove duplicate const lastUpdated declaration that broke JS parse The v0.4.0 UI refactor left two top-level const lastUpdated declarations; a SyntaxError at script parse time took down the whole quota page. Also added a node --check based syntax verification to the release flow.	2026-09-20 12:59:46 +08:00
yuez	553226c96e	feat: multi-key OpenCode Go usage + quota page redesign, bump v0.4.0 - support multiple OpenCode API keys for Go usage and quota queries - redesigned quota page UI - update README and tests	2026-09-20 10:50:06 +08:00
yuez	61c50280b1	feat: add OpenCode Go usage query with aggregated /all endpoint, bump v0.3.0 - New provider: OpenCode Go (GET https://opencode.ai/zen/go/v1/usage, Bearer auth) - Extract shared transport doUpstreamRequest (host.http.do first, net/http fallback) - New management routes: GET/POST /plugins/commandcode/opencode/usage, GET/POST /plugins/commandcode/all - /all aggregates both providers sequentially with partial-failure semantics (>=1 success -> 200, all-local-missing -> 400, all-upstream-failure -> 502) - QuotaCard UI: tabs (Command Code / OpenCode Go / All), OpenCode window cards, version badge v0.3.0, OpenCode API key test override in settings drawer - Config: opencode_api_key / opencode_api_base (ConfigFields 2 -> 4) - Tests: route-order regression, /all partial failure & misclassification guards, ParseOpenCodeUsage edge cases, host/http transport paths	2026-09-18 09:38:40 +08:00
