kingwl a00d1e0496 refactor(mode): move exit-tool visibility onto the registry restriction layer; register /mode; drop unconsumed surfaces
The master merge brought the tool registry's per-scope restriction layer
(tools.restrict), which makes dsh-mode's prepend assemble filter a duplicate
enforcement shape: it re-implemented the registry's SDK-section rendering
(renderToolsSdk + the RUN_CODE_NAME exclusion) and hid the exit tool from
prompts only — dispatch stayed open and the execute-time re-check was the
real gate. The service now reconciles a per-agent deny restriction on
agent.ctx at agent/created and at every boundary flush, so wire schemas, the
Code Mode tools:sdk section, AND dispatch resolve exit_plan_mode through the
one registry view (a default-mode call answers UNKNOWN_TOOL, byte-identical
to a no-dsh-mode deployment). The execute-time folded-mode re-check stays as
defense in depth for a direct foreign mode/set append no boundary has
reconciled yet.

Two zero-consumer surfaces removed per the pre-release stance:
- AgentOptions.mode creation seeding (declaration merge + agent/created
  listener); a caller selects through set() before the first turn, and the
  deferred subagent inheritance returns together with its consumer.
- The dropped-definition boundary notice (droppedNoticed + narration):
  custom mode definitions have no production consumer, so nothing can be
  dropped; fold-to-default degradation is unchanged.

The stdio removal had left plan mode ACP-only while docs still claimed a
/mode command. dsh-mode now registers /mode on the plugin-owned command
registry through an optional ctx.inject(['commands']) child (type-only peer
edge on dsh-commands), so the TUI and the ACP slash-command surface both
gain it; examples/tui-agent composes dsh-mode. ACP/TUI expected outputs
refreshed keyless for the available_commands_update delta.

Docs updated in place (mode READMEs, the plan-mode Agent Note's realization
sections); catalogs and graphs regenerated.

mode/ — session-mode policy family

Session modes: named, logged, per-agent collaboration states, with plan mode as the first shipped definition. A single product package — there is no interface/implementation seam here, because a mode's variable part is a config value (the section text), not a swappable implementation.

Package Role ctx key
mode/ mode/set vocabulary + fold, the ctx.modes service (list/get/set with the turn-boundary flush), the mode:policy guidance section, and the model-facing exit_plan_mode review tool ctx.modes

The mode in force is a pure function of the session log (SessionEventMap['mode/set'], last one wins), so resume and fork restore it with no extra machinery; the default mode is the absence of policy, keeping the plugin invisible until a mode is set. UIs read flips off session/event; the ACP bridge maps the vocabulary to the session-mode picker, and a composed command registry gains the plugin-registered /mode command. Design: plan-mode Agent Note.
