feat(plan): keep exit_plan_mode declared after the first plan-mode entry

Disclose the exit tool progressively instead of following every plan-mode
transition. The plan projection records whether a logged plan/mode ever
activated plan mode (stateVersion 4), and the tool's condition admits it
for a step whose selected state is active or once the Session has entered
plan mode. Leaving plan mode now changes only the guidance section, so an
addition-only route no longer drops a declaration from its cached prefix.

A call while plan mode is not committed still fails as unavailable outside
plan mode, and a Session that never entered plan mode does not list the
tool. The Web plan-review fixtures return to master's recording because the
request tool lists no longer change on exit.

## The exit tool and the `/plan` command
[`exit_plan_mode`](../tool-catalog.md#deepseek-aidsh-plan-mode) is admitted only for steps whose selected plan state is active, so entering or leaving plan mode changes the request tool declarations and the plan guidance together; Native and PTC execution use the same admitted set, and a call outside plan mode returns `UNKNOWN_TOOL`. In plan mode it requires a complete markdown plan starting with a `#` heading and presents it for review through the [user-questions seam](user-questions.md). Approval returns `{ approved: true }` and records a silent (non-narrated) pending exit that is appended at the next accepted in-turn pre-step. Plan guidance therefore remains active for the rest of the assistant's current tool batch, and the tool result itself reports the transition. Keep-planning is a failed call carrying the user's feedback, so the model revises and presents again. A dismissed review returns `{ approved: false }` and concludes the turn, so plan mode stays active until the user's next message. A missing interaction channel and a service reload during review also fail the call rather than silently leaving plan mode.
[`exit_plan_mode`](../tool-catalog.md#deepseek-aidsh-plan-mode) is disclosed progressively: it is admitted from the first step whose selected plan state is active and stays admitted for the rest of the Session, so the first plan-mode entry adds it to the request tool declarations and later transitions change only the plan guidance. Native and PTC execution use the same admitted set; a call before the first entry returns `UNKNOWN_TOOL`, and a call while plan mode is not committed fails. In plan mode it requires a complete markdown plan starting with a `#` heading and presents it for review through the [user-questions seam](user-questions.md).

A missing interaction channel and a service reload during review also fail the call rather than silently leaving plan mode.
When [`ctx.commands`](commands.md) is composed, the plugin registers `/plan [off|message]`: bare `/plan` selects plan mode, any other non-empty message selects it and then submits the text through `agent.steer()` so it becomes the next step's ordinary logged user message under plan guidance, and the exact argument `off` selects inactive, which also cancels a pending entry before it is appended and becomes visible to a request.

Model tool calls run only through their step's admitted set. A call to a conditional tool without a resolved set, a call after the set is disposed, and a pending call whose registration was replaced or removed during the step return `UNKNOWN_TOOL` instead of running.

`exit_plan_mode` is declared from the first step whose selected plan state is active and stays declared for the rest of the Session, so requests of a Session that never entered plan mode no longer list it. Existing Sessions require no format migration.
## Migration
1. Replace tool filtering in `system-prompt/assemble` listeners with a `when` condition on the registration; read the step's provider, model, and reasoning effort from the condition's `modelSelection`. Keep only section, context, and variable changes in the waterfall.
2. Make tool guidance follow the same admission: section callbacks pass `context.toolSet` to `ctx.tools.get()` or `ctx.tools.schemas()`.
3. For programmatic calls of conditional tools, call `ctx.tools.resolve({ agent, modelSelection, signal })`, pass the returned `toolSet` to `assemble()` and `ctx.tools.execute()`, and dispose it after the batch settles.
4. Update expectations that listed `exit_plan_mode` outside plan mode. Verify that a disabled tool is absent from the request, that calling its name returns `UNKNOWN_TOOL` without reaching the implementation, and that a failing condition ends the turn with `TOOL_ACTIVATION_FAILED`.

1. 把 `system-prompt/assemble` 监听器中的工具过滤改为注册时的 `when` 条件;从条件的 `modelSelection` 读取该步骤的提供方、模型与推理强度。waterfall 中只保留段落、上下文与变量的修改。
2. 让工具指引跟随同一准入:段落回调把 `context.toolSet` 传给 `ctx.tools.get()` 或 `ctx.tools.schemas()`。

#### KV Cache effect
Entering plan mode adds the exit tool through the route’s tool-update protocol, and leaving removes it. An `in-history` route records both changes after cached history. An `addition-only` route, such as the default catalog’s `deepseek-flash`, cannot record the removal and drops the tool from later requests, so the first request after leaving can miss part of the cached prefix; a route without tool updates resends its changed declaration list after either transition. Plan arguments and review results extend the conversation normally.
