feat(monaco): 报错治理 + diff 滚动条总览标尺（体验优化）#85
Merged
Conversation
只用 Monaco 做只读 diff + 语法着色（着色走 tokenizer，与语言服务无关），不需要补全 / 悬浮 /
符号 / 诊断等。但内置 typescript/javascript · json · css/scss/less · html/handlebars/razor 这 4
个带 worker 后端的语言族会主动向对应 *.worker 发 RPC（getNavigationTree / getSyntacticDiagnostics /
doValidation …），而我们只注册 base editor.worker → 找不到 handler，抛 `Missing requestHandler
or method: …`（此前靠 window 兜底降级为 console.warn）。
对这 4 族各 *Defaults 传空 ModeConfiguration（字段全 optional，缺省即不注册对应 provider），
从源头不再产生这类 RPC，整族报错消失；window 兜底退化为纯保险。其余 80+ 语言是 monarch
tokenizer 纯着色、无 worker，不受影响。着色不依赖语言服务，ts/js/json/css/html 仍正常上色。
注：contribution 子模块运行期具名导出 *Defaults，但 .d.ts 误为 `export {}`（monaco 0.55 ESM
打包缺陷），故 namespace 引入 + 经 unknown 转已知形状取用，不引入 any。

不走 diff 专属的 renderOverviewRuler 宽列（并排会多出独立列），改用编辑模式风格：内层编辑器 自带的 overview ruler（overviewRulerLanes=3 → 按 1/3 分道，中间留白）+ 装饰投影。 - DiffPane：关 diff 合并标尺、显式 3 道，色条更细、minimap 保持关闭 - useDiffOverviewMarks：diff 增/改绿（左道，按行高）、删红；并排红画在左侧 original 编辑器 ruler，统一视图红 tick 与绿同走左道（被删行是 view zone 无 model 行，只能在删除点点标） - useCommentZones：评论锚点装饰加 overviewRuler 投影到右道（蓝），滚动条一眼可见哪些行有评论 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
`Missing requestHandler …`（已从源头关闭语言服务，留作双保险）与 `TextModel got disposed
before DiffEditorWidget model got reset`（DiffEditor 切换 model 的 dispose 竞态）均为 Monaco
上游已知问题、不影响渲染、应用侧无法根除，作为已知问题默认静默（不再打 console.warn 噪音）。
需诊断时 localStorage.setItem('meebox.monacoDebug','1') 再刷新即可看到被吞的报错明细。

背景
一组 Monaco 体验优化：消除 console 噪音报错，并让 diff 的增删 / 评论锚点在滚动条总览标尺上一眼可见（不启用 minimap）。
三笔独立 commit：
1.
refactor(monaco)从源头关闭带 worker 后端的语言服务只用 Monaco 做只读 diff + 语法着色（着色走 tokenizer，与语言服务无关）。typescript/javascript · json · css/scss/less · html/handlebars/razor 这 4 族会主动向对应
*.worker发 RPC（getNavigationTree/getSyntacticDiagnostics/doValidation…），而只注册了 base editor.worker → 抛Missing requestHandler or method: …。对这 4 族传空 ModeConfiguration（字段全 optional，缺省即不注册 provider），从源头消除整族报错。着色不受影响。2.
feat(diff)滚动条总览标尺展示 diff 增删与评论锚点不走 diff 专属的
renderOverviewRuler宽列（并排会多出独立列、偏宽），改用编辑模式风格：内层编辑器自带 overview ruler（overviewRulerLanes=3→ 按 1/3 分道、中间留白）+ 装饰投影。3.
chore(monaco)benign 报错默认静默 + debug 开关Missing requestHandler …（已从源头关闭，留作双保险）与TextModel got disposed before DiffEditorWidget model got reset（DiffEditor 切换 model 的 dispose 竞态）均为 Monaco 上游已知问题、应用侧无法根除 → 作为已知问题默认静默（不再打 console.warn 噪音）。需诊断时localStorage.setItem('meebox.monacoDebug','1')再刷新即可看到被吞明细。仅命中两条白名单消息，其它异常照常抛出。验证
lint零警告 ✓ ·typecheck✓ ·build✓ ·test（仅 packages；repo-mirror 5 个 git-CLI 环境性失败属已知、与本改动无关）。关联里程碑 体验优化 (#4)。
