内置加速通道换新代理 + 架构决策：Web 端独立成支。 New acceleration proxy for the built-in channel, plus an architecture decision: Web moves to its own branch.

架构决策 / Architecture

  • Web 端独立：独立分支 web + 独立 lib/ + 独立 workflows。
    • 不共用代码：web 端不复用 main 的 lib/；
    • 不共用 actions：web 端不跑 build.yml / ci.yml；
    • 允许反复失败：web 失败不影响 main 的五平台构建与发布。

      Web lives on its own branch with its own lib/ and its own workflows — no shared code, no shared actions, and it may fail as often as it needs without ever affecting the five-platform release.

  • 平台能力下沉为原生实现（下一阶段）：原先由 action 里的 inject_*.py 改平台工程的做法，改为原生 Dart 实现，action 退化为可选编译开关。 Platform capabilities move from action-time injection to native Dart implementations; actions degrade to opt-in compile switches.

变更 / Changed

  • 内置加速通道改走 gh.felicity.ac.cn 转发完整 GitHub 链接：优先前缀由 https://gh.344977.xyz/ 改为 https://gh.felicity.ac.cn/https://github.com/； https://gh.felicity.ac.cn/ 保留为降级备选，仍按序探测并静默降级， 最后永远保留直连兜底。 The built-in channel now forwards the full GitHub link through gh.felicity.ac.cn; the bare host stays as a silent-fallback option.
  • 更新日志站（changed/）全部 Release 下载链接改为同一形式。 All changelog-site download links now use the same form.

移除 / Removed

  • 实验性 Web（wasm）构建管线从 main 移除：Web 改由独立分支承接。 The experimental Web (wasm) pipeline is removed from main; Web moves to its own branch.
