docs(pm-dispatch): give the domain:ui lane its versioned job description (#17243)

`references/lanes/` held nine job descriptions and `domain:ui` — the one lane
the multi-repo charter itself adds, with the widest residual scope of the three
objectui streams — had none, while SKILL.md rules that 范围与常设承诺 are
versioned in `references/lanes/<lane>.md`.

Adds `references/lanes/ui.md` in the directory's own shape (形态 / 范围 /
常设承诺 / 席内判断), written as pointers to the rules already stated in
SKILL.md 〈多仓协调〉 and objectui's AGENTS.md §9 — no rule is restated, so no
concept gains a second source of truth. 席内判断 are the seat's own standing
tests, taken from the live `domain:ui @ objectui` seat post.

Registers the new file in the line ratchet: one `CEILINGS` row seeded at the
landed count of 38 (headroom 0) and one table-row pin at 0 (the file carries no
table). Registration only — no existing ceiling or pin moves.

+# 车道岗位说明:domain:ui
+
+见 SKILL.md 〈多仓协调〉;本文是本席的岗位说明,现值状态恒在座位贴,⛔ 不迁入本文件。
+
+## 形态
+
+- 本席为姊妹仓执行座位:在 objectui 仓认领、派发、复核、落地。
+- ⛔ 不产 `domain:*`、type 与定级,中央分诊唯一生产,见 SKILL.md 多仓协调规则 1 与 4。
+- 误标 ⛔ 不自改:挂 `pm:retriage` 加异议评论同笔,见同节规则 4。
+
+## 范围
+
+- 三流分流的残余流归本席:发布库 `@object-ui/*` 与 `apps/*`,判据见 SKILL.md 〈多仓协调〉。
+- objectui 的 `domain:devx` 与 `domain:spec` 卡归各自跨仓车道,⛔ 不归本席。
+- 症状位置不改流向,docs 随所记录的面走,两条同上节,⛔ 不在此另抄。
+- 落点不明留分诊首触,⛔ 不猜、不代判。
+
+## 常设承诺
+
+- 构建产物经 `pnpm objectui:refresh` 回流,见 SKILL.md 〈多仓协调〉。
+- 回流后的 console pin bump 是 objectstack 的单张卡,⛔ 永不做本仓 PR 的 rider。
+- 凡触 `packages/spec` 一律转 `domain:spec` 座位,见 SKILL.md 〈多仓协调〉。
+- `scripts/pm/**` 单写手恒在 objectstack 侧 ⇒ 本席的工具需求走上游卡带 `Blocked-by:` 回链。
+- 受管面五项含仓根发布 `skills/**`,清单、判据与禁令见 objectui AGENTS.md §9 受管面段。
+- ⇒ 命中即整 PR 停在 draft 等人合,⛔ 不 ready、不入队、不 auto-merge、不自合、不留批准。
+- 未命中的 PR 按同节走合并队列落地;changeset 与版本纪律见 objectui AGENTS.md §9。
+- 半状态巡查在本仓有载体:定时 workflow 与 sweeper 皆在,自 objectstack 移植。
+- 锚 issue 未配置 ⇒ 写锚步骤 skip,发现只落 run summary,绿不等于已交付读锚腿。
+- ⇒ 手工半边照 `hotcrm.md` 那条办,并每轮实测锚是否已配,⛔ 不沿用本行读数。
+
+## 席内判断
+
+- 卡正文是快照不是状态:⛔ 不凭正文单读裁决或派发,读全线程并对 `origin/main` 重测。
+- `pm:queue` 在本仓兼指已分诊与可派发 ⇒ 逐张重验可派性,⛔ 不按标签直派。
+- 零读数恒配点亮的正控,且正控须经被测机制本身生效;本仓 search 假零,查重只引命中。
+- 脚本能滚动不证明用户能滚动:可达性断言必须驱动真实输入管道。
+- 落地验证按内容,正控须在合并前证明会响,⛔ 不按 sha 判已落地。
+- 档位与复核豁免边界读源码与 `references/contract-review.md`,⛔ 不凭记忆或继承的注记。
