release: prepare v2.1.6 beta (qimen calendar + India map-pick) + batch issue #2

Sync two Mac-side fixes (Mac main 494783d / v2.1.6) into Windows and batch in
the Windows-only issue #2 fix committed earlier (98bea3f).

- Qimen 奇门 calendar (issue #4, vendored Python vendor/kinqimen): jieqi.py
  gangzhi corrects the month pillar by sxtwl's precise 交节 time (births before
  the crossing keep the previous day's pillar; 立春 also corrects the year
  pillar) + new zhirun_jieqi (超神接气置闰 ju-determination); config.py rewrites
  qimen_ju_name_zhirun + adds dingju_jieqi; kinqimen.py pan() 節氣 label via
  dingju_jieqi; test_qimen_calendar.py (11 tests). 拆补 method unchanged.
- India chart (issue #3): IndiaChartMain.js changeGeo sends a flat patch
  matching the parent changeCond (was wrapping lat/lon as {value:...}).

No Java change -> astrostudyboot.jar NOT rebuilt; the qimen fix ships in the
runtime payload (verified: app-runtime.tar carries zhirun_jieqi). Bump to 2.1.6.

Verified: qimen 11/11 on the embedded python; frontend build:file + umi-test
28 suites / 129 tests; service-manager 18/18 (issue #2 env isolation);
release_selfcheck.py 5/5 (added qimen + India sentinels). The 4 modified files
were byte-identical to the Mac-2.1.5 baseline (zero Windows divergence); the
test file is a pure add.

-这一版把 Mac 端最新的 **AI 分析页全面修复** 同步到 Windows（供应商切换 / 鉴权、发送安全、静默失败透出）：
+这一版把 Mac 端的 **奇门历法底层修复** 与 **印度盘地图选点修复** 同步到 Windows：
 
-- **多供应商切换更顺**：供应商卡片可点击 + 「设为当前」按钮；切换供应商类型会清空旧 API key；删除当前供应商自动补选另一个。
-- **Gemini 直连修复**：原生 Gemini 走 URL `?key=`，不再误加 `Authorization` 头（此前会报 `ACCESS_TOKEN_TYPE_UNSUPPORTED`）；custom 供应商可用 `providerOptions.authHeaderName` / `authPrefix` 自定义鉴权头；推理模型前缀新增 `o5`。
-- **发送更稳**：流式生成中再按回车不会并发重发；切换 / 删除会话会先中止当前流；新消息自动滚到底部。
-- **失败不再静默**：嵌入 / 分块失败有提示；Markdown 解析失败退回纯文本；请求超时可由 `providerOptions.requestTimeoutMs` 配置；本地存储配额超限会记录日志而非吞掉。
+- **奇门月柱交节边界**：月柱改为按 sxtwl 精确交节时刻判定——交节当日、交节时刻之前的时间不再被错算进新月（立春同时校正年柱）。例：2005-05-05 16:30 月柱由辛巳更正为庚辰。
+- **奇门置闰超神接气定局**：置闰法定局改用「超神接气置闰后的节气」（新增 `zhirun_jieqi`），弃用旧农历启发式（旧实现约 45% 日期误用当日历法节气）。例：2027-10-31 由霜降更正为立冬上元六局；拆补法本就正确，未改。
+- **印度盘地图选点修复**：印度盘在地图上选点后排盘不再报错（`changeGeo` 传参对齐父级 `changeCond`）。

-> This release syncs the latest Mac-side **AI Analysis page hardening** into Windows (provider switching/auth, send-safety, surfaced failures): clickable provider cards + a "set current" button, switching provider type clears the stale API key, deleting the current provider auto-selects another; native Gemini uses the URL `?key=` and no longer adds an `Authorization` header (which caused `ACCESS_TOKEN_TYPE_UNSUPPORTED`), with `authHeaderName`/`authPrefix` overrides for custom providers and an added `o5` reasoning prefix; pressing Enter mid-stream no longer double-sends, switching/deleting a session aborts the stream first, and new messages auto-scroll; embedding/chunking failures are surfaced, Markdown parse failures fall back to plain text, request timeout is configurable via `providerOptions.requestTimeoutMs`, and a localStorage quota overflow is logged instead of silently swallowed. The backend `AIAnalysisProxyService` change was rebuilt into `astrostudyboot.jar`. Still includes the 2.1.4 / 2.1.3 / 2.1.2 / 2.1.1 work. See the [v2.1.5 release](https://github.com/Horace-Maxwell/Horosa-Web-App-comprehensively-improved-Windows/releases/tag/v2.1.5) for the full log.
+> This release syncs the Mac-side **Qimen (奇门) calendar fix** and **India chart map-pick fix** into Windows. Qimen month-pillar now respects the precise 交节 (solar-term) crossing time — births before the crossing are no longer pushed into the new month, and 立春 also corrects the year pillar (e.g. 2005-05-05 16:30 月柱 辛巳→庚辰); 置闰 ju-determination now uses the 超神接气置闰 solar term (new `zhirun_jieqi`) instead of the old lunar heuristic that was wrong ~45% of the time (e.g. 2027-10-31 霜降→立冬上元六局), while the 拆补 method was already correct and is unchanged. The India chart no longer errors after picking a location on the map (`changeGeo` now matches the parent `changeCond`). The Qimen changes live in the vendored Python engine (`vendor/kinqimen`) shipped with the runtime — no Java change, no jar rebuild. Still includes the 2.1.5 / 2.1.4 / 2.1.3 / 2.1.2 / 2.1.1 work, plus a Windows-side issue #2 fix isolating the embedded Python/Java runtime from a contaminated host environment (Win11 machines with system Python no longer fail to launch). See the [v2.1.6 release](https://github.com/Horace-Maxwell/Horosa-Web-App-comprehensively-improved-Windows/releases/tag/v2.1.6) for the full log.
