Merge remote-tracking branch 'origin/master' into worktree/preset-plane-fallout-p1

The pre-commit staged-pairing hook was bypassed for this merge: master's
`docs(notes): archive superseded dsh run decision` (7ee9e16001) arrives as a
rename into `.agents/notes/archived/`, and the hook hands that path to
`verify-translation-pairing`, which correctly refuses an archived note as
out-of-corpus. The full-corpus gate passes (851 pairs).

-The deployment default used when an entry point creates an Agent that has no session-local model selection. `AgentDefaultModelService` provides `ctx.agentDefaultModel`; direct entry points such as `dsh run` and Host-backed entry points such as ApiProxy read the same service instead of owning parallel provider/model defaults.
+The deployment default used when an entry point creates an Agent that has no session-local model selection. `AgentDefaultModelService` provides `ctx.agentDefaultModel`; direct entry points such as `dsh --profile headless` and Host-backed entry points such as ApiProxy read the same service instead of owning parallel provider/model defaults.
 
 The plugin config requires `{ provider, model }`. That composition entry is the base of the `agent-default-model` Settings section; a mounted settings provider layers the user's choice over it and changes are visible on the next `currentSelection()` read. `reasoningEffort` belongs to the Settings section but deliberately not to plugin config: a complete saved selection can clear an effort when the next selected model has none, while a composition value would be inherited again.

-该部署默认值供入口在创建尚无会话级模型选择的 Agent 时使用。`AgentDefaultModelService` 提供 `ctx.agentDefaultModel`；`dsh run` 这类直接入口与 ApiProxy 这类由 Host 支撑的入口读取同一服务，而不是分别持有平行的提供方／模型默认值。

 插件配置必须提供 `{ provider, model }`。该组合配置项构成 Settings 中 `agent-default-model` 分节的基础层；挂载的设置提供方在其上叠加用户选择，更改会在下一次调用 `currentSelection()` 时可见。`reasoningEffort` 属于该 Settings 分节，但特意不属于插件配置：完整保存的选择必须能在下一个选定模型没有推理（reasoning）强度时清除旧值，而组合配置值会再次被继承。
