fix(dashboard): keep clickable execution chip compact

[Duang777]

Problem

PR #5341 changed the execution chip from a span to a button and gave the desktop button a 28px minimum height. The packaged browser smoke still enforces the existing 26px compact-row contract, so current main fails with Execution chip is not a compact hairline row: 28px tall.

Main failure evidence: https://github.com/loopx-project/loopx/actions/runs/36691337881/job/109809017646

Change

• Restore the desktop button minimum height to 26px.
• Keep the 44px mobile touch target unchanged.
• Preserve the button semantics, hover state, focus ring, and settings interaction from fix(chat): verify intent before handoff and adopt model edits #5341.

Verification

• npm run build
• LOOPX_PERSONAL_WORKSPACE_SCENARIO=execution-chip npm run smoke:personal-workspace-packaged
• python scripts/chat_bundle.py verify --source
• git diff --check

The packaged browser scenario passed on top of main@7e60e6999, including the 26px desktop assertion and 390px mobile viewport checks.

Exact-head CI is green on c33543eaae57f33e28c82f0c85be27216bbe785b (20 passing checks, no failures or pending jobs).

The checks include Frontstage Pages, Release Artifacts, macOS and Windows desktop builds, dashboard-acceptance, chat-bundle-browser, all three TypeScript shards, TypeScript coverage, and merge-gate. This independently clears the repeated Execution chip is not a compact hairline row: 28px tall baseline failure seen on #5338 and #5344. The mobile 44px rule remains unchanged.

Ready for maintainer review; no merge action was taken.

@huangruiteng @maxliux5 This exact head remains fully green and is now the dependency blocking #5344 from resolving its main conflict without retaining the old execution-chip baseline failure. Please review when available. No merge action has been taken.

APPROVE — exact head c33543e; immutable base 7e60e69.

动机

这次修复针对一个已复现的显示回归：执行信息从文字变成可点击按钮后，桌面最小高度升到二十八像素，违反现有的二十六像素紧凑行约束。目标是恢复次要元信息的视觉权重，同时保留一键进入设置与移动端触控面积；不是重做工作区。

改动思路

复用现有样式和交互所有者，只把桌面按钮最小高度恢复到既有上限，不改组件、设置状态或权限。实际路径仍是工作区页头到 Steward 设置，再返回工作区，不增加信息重填或确认步骤。移动端后置媒体查询保留四十四像素；没有回调的只读路径仍展示文字，不凭样式获得写权限。

具体改动

关键代码讲解

1. apps/presentation/dashboard/src/features/personal-workspace/personal-workspace.css:211 的 button.personal-execution-chip 是唯一修改点：桌面最小高度从二十八改为二十六，悬停、焦点轮廓与边框规则保持不变。相邻移动端覆盖仍使用四十四像素，不能把桌面压缩误读成触控目标缩小。
2. apps/presentation/dashboard/src/features/personal-workspace/channel-header.tsx:9 的 ChannelHeader 是实际消费者。它在已有设置回调存在时生成按钮，否则保留文字分支；按钮继续调用原来的设置导航，不提交配置。已检查工作区页面的设置入口与返回路径，没有新增状态所有者、备用写入路径或不可达的抽象。

对主干的风险

主要风险是桌面压缩连带损伤移动端或键盘操作。我亲自构建两端相同夹具：旧基线原生 packaged smoke 明确因二十八像素失败，当前 head 通过；独立浏览器读到桌面二十六、移动端四十四，均无横向溢出。整屏检查、键盘 Enter 打开设置和返回均完成，独立回读配置写入计数为零。当前 build、bundle verify、已有 packaged scenario、diff check 通过。构建的大 chunk 提示基线也存在，不是失败或本 PR 阻塞。使用真实构建前端和合成 API，不声称已安装 App、真实后端持久化或线上排序已验证；这些所有者未变。

我的整体评价

这一行足以完整修复当前回归，长期运行影响为保留，用户体验为改善；未增加步骤、协议或义务。未来向简化检查认为已有样式与 smoke 已能定位问题，无需额外组件或测试框架。无可发布的阻塞发现；这不是 opt-in 功能，也没有权限或类型化状态语义变化。评审未查询或等待远端 CI，APPROVE 不代表代替维护者合并或安装。

English verdict: APPROVE - The exact-head one-line desktop fix is validated against the immutable base, preserves mobile and keyboard access, and changes no runtime authority.

Merge-readiness requalification (not a new review)

Exact head: c33543eaae57f33e28c82f0c85be27216bbe785b. The existing exact-head approval remains valid; this action reuses that review rather than inventing a new verdict or claiming new UI validation.

The current loopx pr-review --check-merge-readiness result is not ready, with only merge_state_requires_update: GitHub reports BEHIND. Update the branch against its base, then qualify/review the resulting new exact head before a maintainer merges. No merge or admin bypass was performed.

CI policy is not_consulted; this base-update hold is not a REQUEST_CHANGES finding and is not an assertion that unrelated red CI was caused by this PR.

中文：当前精确-head 批准继续有效；这次是 capability 指定的合并就绪复查，不重复提交评审。当前仅因分支落后主干而暂不就绪，请更新分支后对新 head 复核，再由 maintainer 合并。没有合并，也没有把无关红 CI 作为 Request Changes 理由。
