Turtle aeb48cc5f3 Render error cause chains at every diagnostic seam
A TUI run against an unreachable endpoint failed with only 'fetch failed':
undici wraps transport failures in a bare TypeError whose diagnosis lives
on .cause, and every diagnostic seam rendered only error.message. The
readline front door additionally rendered failed turns as pure silence.

- dsh-llm: new errorChain(value) renders the full cause chain and
  AggregateError members with circular/hostile-coercion containment.
- llm-deepseek: pre-response transport failures throw LlmError('NETWORK')
  naming the endpoint and chaining the fetch TypeError; aborts keep their
  DOMException so the loop still classifies them as cancellation.
- agent-loop: durable turn/end error messages and logger warnings render
  through errorChain; local renderThrown copies removed.
- ui-stdio: failure turn/end reasons now render ([turn failed <code>],
  [turn aborted], [turn rejected], output-token-limit); startup-failure
  logs use errorChain.
- ui-tui: agent/error notices and the startup-failure line use errorChain.

# ctx.agentLoop
`AgentLoop` — provided by `@deepseek-ai/dsh-agent-loop`.
Concrete agent factory and driver service.
[Source](https://github.com/deepseek-harness/deepseek-harness/blob/master/packages/core/agent-loop/src/index.ts#L398)
### ctx.agentLoop.create(id, options?, meta?)
```ts website-api
/**
* Create an agent and session under one caller-supplied identity, owned by
* the accessing fiber. Constructor-driven config calls mint a fresh combined
* id before entering this boundary.
* @param id - shared agent/session identity.
* @param options - concrete loop options.
* @param meta - optional fresh-session workspace metadata.
* @returns the published running agent.
*/
create(id: SessionId, options: AgentOptions = {}, meta: Pick<SessionHeader, 'cwd'> = {}): Agent
```
Create an agent and session under one caller-supplied identity, owned by the accessing fiber. Constructor-driven config calls mint a fresh combined id before entering this boundary.
- `id` — shared agent/session identity.
- `options` — concrete loop options.
- `meta` — optional fresh-session workspace metadata.
**Returns** the published running agent.

### ctx.agentLoop.createAgent(ownerCtx, options)
```ts website-api
/**
* Create an owned agent on a caller-supplied session id.
* @param ownerCtx - caller context that structurally owns the transaction.
* @param options - identities, session seed/metadata, loop options, setup, and cancellation.
* @returns the published handle.
*/
async createAgent(ownerCtx: Context, options: CreateAgentOptions): Promise<AgentHandle>
```
Create an owned agent on a caller-supplied session id.
- `ownerCtx` — caller context that structurally owns the transaction.
- `options` — identities, session seed/metadata, loop options, setup, and cancellation.
**Returns** the published handle.
[Source](https://github.com/deepseek-harness/deepseek-harness/blob/master/packages/core/agent-loop/src/index.ts#L555)
### ctx.agentLoop.resume(ownerCtx, options)
```ts website-api
/**
* Resume an owned agent from the configured persistence service.
* @param ownerCtx - caller context that owns load, setup, and the live lifecycle.
* @param options - persisted identity, loop options, setup, and cancellation.
* @returns the published handle.
*/
async resume(ownerCtx: Context, options: ResumeAgentOptions): Promise<AgentHandle>
```
Resume an owned agent from the configured persistence service.
- `ownerCtx` — caller context that owns load, setup, and the live lifecycle.
- `options` — persisted identity, loop options, setup, and cancellation.
**Returns** the published handle.
