fix(coding-agent): disable undici body/headers idle timeouts on global dispatcher

Browse Source 
Long local-LLM SSE streams (e.g. vLLM buffering large tool calls) exceeded
undici's default 300s bodyTimeout and aborted with UND_ERR_BODY_TIMEOUT.
retry.provider.timeoutMs cannot lift this cap because it controls the
provider SDK's AbortController deadline, not undici's per-socket idle timer.

Pass { bodyTimeout: 0, headersTimeout: 0 } to EnvHttpProxyAgent. Provider
SDKs still enforce their own timeouts via retry.provider.timeoutMs.

- Fixed `/tree` cancellation via `session_before_tree` leaving the session stuck in compaction state ([#3688](https://github.com/badlogic/pi-mono/issues/3688))
- Fixed Escape interrupt handling when extensions hide the built-in working loader row ([#3674](https://github.com/badlogic/pi-mono/issues/3674))
- Fixed coding-agent test expectations for current default models and missing-auth guidance.
- Fixed long local-LLM SSE streams aborting at 5 minutes with `UND_ERR_BODY_TIMEOUT` by disabling undici `bodyTimeout`/`headersTimeout` on the global dispatcher; provider SDKs continue to enforce their own deadlines via `retry.provider.timeoutMs` ([#3715](https://github.com/badlogic/pi-mono/issues/3715))
