lintianle efba9fab0a website: generate the API reference from source (cordis + all 15 harness services)
scripts/gen-website-api.ts renders website/zh-CN/api/{cordis,harness}/* and the
api-sidebar.json fragment the VitePress config imports, so pages and navigation
can never drift from the code: signatures, @param/@returns prose, dispatch
modes, and GitHub source links are extracted, never transcribed, and the
generator hard-errors on any rendered member missing docs. verify-website-api
(doc-sync + run-gates) is the freshness gate.

Replaces the hand-written zh api pages (7 pages covering 7 of 15 services,
with phantom APIs: Context.current/Context.events, agent/post-step, tool/call,
compact/*, llm/pre-request none of which exist) with generated English
references: 5 cordis pages, 15 per-service pages, and a 35-event catalog
grouped by scope. The hand-written hub api/index.md stays and now indexes the
full surface; zh for these pages arrives with the unified translation flow.

# ctx.codeRuntime
`CodeRuntime` (abstract seam) — provided by `@deepseek-ai/dsh-code-runtime`.
Abstract code-execution service. Subclass, implement run and the two descriptors, and load the subclass as a plugin — it registers as `ctx.codeRuntime` (one implementation per context; loading a second throws, cordis' standard duplicate-service behavior).
Semantics every implementation must honor:
- run resolves with an error FIELD for every program outcome — parse/transform failures, thrown exceptions, budget expiry, abort, substrate death (CodeRunFailure's taxonomy). It REJECTS only for caller misuse of the seam itself (e.g. a run submitted after disposal).
- Binding calls bridge to the caller's CodeBindingFunctions verbatim; arguments and resolutions must be structured-cloneable, and the runtime treats the program as a hostile peer (arbitrary binding names are own properties, malformed traffic is rejected or ignored, never crashes the host).
- Runs are isolated from each other: no state survives from one run to the next through the runtime.
- Disposal reaches quiescence: in-flight runs are terminated AND awaited before the service's own teardown completes (no orphan substrate survives `fiber.dispose()`).

### ctx.codeRuntime.run(request)
```ts website-api
abstract run(request: CodeRunRequest): Promise<CodeRunResult>
```
Execute one program against the request's bindings and capture what it emitted. See the class doc for the resolution contract (error is a result field; rejection means seam misuse only).
- `request` — the program, its bindings, and the abort signal; the request carries everything the runtime acts on, with no hidden defaults.
**Returns** the run's outcome: completion value (when transferable), the ordered log capture, and the failure (if any).
