Yichen Jiang fe221be572 Merge remote-tracking branch 'origin/master' into worktree/preset-plane-fallout-p1
The vendored Cordis rescope (`cordis` -> `@deepseek-ai/cordis`,
`@cordisjs/plugin-*` -> `@deepseek-ai/cordis-plugin-*`) collided with this
branch's two added edges. Resolved by taking master's package names and
keeping this branch's additions: `@deepseek-ai/dsh-agent` and
`@deepseek-ai/dsh-system-prompt` peers, the `scopeChainOf` import, and the
`agent/created` type-only edge.

`docs/event-producer-consumer.*` is generated; regenerated after the merge
rather than hand-resolved.

/**
* Agent-plane presentation selector: the row an agent preset carries to say
* which form of its tools the model sees.
*
* The tool registry itself stays on the host plane — the agent loop's
* scheduler, the API proxy's presenters, and every tool plugin are all its
* consumers, so it cannot move into a preset. What a preset CAN own is the
* presentation: `ctx.tools.presentAs()` declares it for the mounting SCOPE,
* which is the preset's standing mount, so the declaration covers every agent
* joined to that preset and a Code Mode preset runs beside native ones in one
* process. One row per composition, not one per session.
*
* A code mode needs a TypeScript code runtime, which is a host-plane service
* ([`dsh-code-runtime-worker`](../../code-runtime/code-runtime-worker/README.md)).
* This row therefore waits for it rather than assuming it: a preset selecting
* Code Mode against a deployment that composes no runtime fails at mount, named
* in the preset's own activation audit, instead of at the first prompt.
* @module @deepseek-ai/dsh-agent-tool-mode
