fix(client): review fixes for invocation rendering and turn boundaries

The user-turn predicate (opensUserTurn) unifies the three parallel
consumers a new node kind silently missed — produced-files turn reset,
retry liveness, own-words force-scroll — so a skill invocation behaves as
the turn opener it is. The menu marker resolves through ctx.locale.bind
instead of a hand-rolled snapshot lookup; the dead legacy <skill> render
arm goes with the removal cut; command-over-skill name precedence is now
documented at the matchEnter seam; and the emptied replacement catalog
keeps the no-reload sentence, with the never-published residual recorded
in the Agent Note.

 Skill invocation source, browser half: registers the `/`-trigger `skill` source into `ctx.slash`. Ordinary-session candidates come from the `skill.list` RPC addressed by the per-call `ClientSessionContext` projection's `{sessionId}`, with the host resolving `cwd` from the session header. The host serves every user-invocable skill; a `modelInvocable: false` entry (a `disable-model-invocation` skill, whose only entry point is this path) wears the user-only marker as a description prefix in the active language. Catalog-addressed continuable children resolve no skill candidates locally because the existing skill RPC requires an attached session; viewing their persisted history must not activate them. Catalogs cache per ordinary session with a single-flight fetch; the scope-birth `warm` hook prewarms the session's entry and `connection/reset` clears everything. Results filter by `startsWith(query)`.
 
-A menu pick or an entered `/name [args]` line claims the composer into an args-tolerant `skill.invoke` transaction (`matchEnter` strong-waits the catalog; an unknown name answers undefined and stays a plain prompt). Submit trims the args, keeps blank args off the wire, and folds an RPC refusal into the composer's error outcome; the host renders the skill body and injects it as a user message before starting the turn, so invocation is deterministic for every user-invocable skill. The RPC rides the plugin's root-context connection captured at registration — the source never reads services off a per-call argument. Draft chip visuals still derive from the `lexicon` scan; the legacy `<skill>name</skill>` reference codec is gone (decision 21 removal cut) and `matchSpace` stays unimplemented — menu and enter own the skill flows.

A skill name shared with a host command resolves to the command: adjudication polls sources in registration order and the web bundle mounts ui-command ahead of this source — deliberate precedence, matching peer products.

 A failed `skill.list` throws from `candidates`, which the slash shell logs and folds into a silent menu-group drop — the menu shows only pending/ready states.

 skill（技能）调用 source 的浏览器端：把 `/` 触发的 `skill` source 注册进 `ctx.slash`。普通会话的候选来自 `skill.list` RPC，以每次调用的 `ClientSessionContext` 投影中的 `{sessionId}` 寻址，host 从会话 header 解析 `cwd`。宿主提供每一个用户可调用的 skill；`modelInvocable: false` 的条目（即 `disable-model-invocation` skill，此路径是其唯一入口）会以当前语言把仅限用户标记作为描述前缀带上。由目录寻址的可继续 subagent 在客户端解析为没有 skill 候选，因为现有 skill RPC 要求会话已挂载；查看其持久化历史不得激活它。目录按普通会话缓存，拉取走 single-flight；scope 创建时的 `warm` 钩子预热该会话的缓存项，`connection/reset` 清空全部缓存。结果按 `startsWith(query)` 过滤。
