fix(lint): 清零存量 lint 告警并接入 CI / Makefile 门禁

存量清理（首跑 141 errors / 21 warnings → 0 / 0）：
- 删除孤儿 disable：SideChatView / Sidebar / selection-popup 三处 exhaustive-deps 豁免与 chunk-artifact 的 no-new-func 豁免（多行理由注释把 disable-next-line 顶离了实报行；selection-popup 改为提取 popupOpen 标志真修复）
- 死代码：未用导入（Sidebar×7、TextEditor、SideCardSection、config、fs-operations 及 6 个 spec）、sidechat-core 死累加器 total、chunk-loader.spec 死助手 registry、sidechat-seed-validation 死助手 toolResultMessage
- 真实小修：agent-opens 三处 throw 补 cause；lazy-chunk any → ComponentType<P>（P extends object）；service.ts claimed 初值改定值赋值；chunk-loader task / spec 内 etag / pendingLoad / snapshot 改 const；terminal-links 去掉字符类内多余转义；SubagentView catalogs 空兜底 useMemo 稳定标识；editor-host.spec 组件提出大写 FakeViewer（rules-of-hooks）；pty-helpers.spec 内联 require 提升为静态导入；panel-host-css 注释里的零宽空格改为可见写法
- 依赖数组豁免（均带理由）：granular scope 字段（EditorHost / PdfView / ChangesTab / GitLens×2）、job.status 粒度（SubagentView×2）、清理期读 ref、mount-only 注册等；ctx（挂载期恒定）直接入 deps（Sidebar×3）、TextEditor previewScroll 补 scope（幂等）
- 刻意控制字符正则（conversation-draft / markdown-images）与宿主槽位 any 签名（context-types）以带理由豁免保留

接入：
- Makefile：lint 目标（typecheck 旁），check 聚合补 lint 保持「对齐 CI」语义
- ci.yml ci / ci-windows 两 job 与 release.yml 在 Typecheck 后加 Lint 步骤（release 注释同步顺序）
