<!-- CURSOR_SUMMARY -->
> [!NOTE]
> Implements request-level tracing for local-agent by threading
`dyadRequestId` through handlers and tool calls, and consolidates engine
API requests.
> 
> - Pass `dyadRequestId` from `chat_stream_handlers.ts` into
`handleLocalAgentStream` and include in `providerOptions`
> - Update `handleLocalAgentStream` signature and `AgentContext` to
include `dyadRequestId`; propagate to `streamText` and tool execution
context
> - Introduce `pro/main/ipc/handlers/local_agent/tools/engine_fetch.ts`
to centralize Dyad engine requests, automatically adding `Authorization`
and `X-Dyad-Request-Id` headers
> - Refactor tools (`code_search.ts`, `edit_file.ts`, `web_crawl.ts`,
`web_search.ts`) to use `engineFetch` and remove per-file API key/URL
handling
> - Adjust tests to supply `dyadRequestId` and validate unchanged
behaviors (errors, streaming, abort, commits, approvals)

## Summary by cubic
Pass the Dyad request ID through the local agent and include it on all
engine tool calls to enable end-to-end request tracing. Centralizes
engine API calls with a shared fetch wrapper.

- **Refactors**
- Added engine_fetch wrapper that sets Authorization and
X-Dyad-Request-Id headers.
- handleLocalAgentStream now accepts dyadRequestId and forwards it to
AgentContext and provider options.
- Updated tools (code_search, edit_file, web_search, web_crawl) to use
engineFetch and removed duplicate URL/API key handling.
- chat_stream_handlers forwards dyadRequestId (fallback:
“[no-request-id]”).
  - Tests updated to include dyadRequestId in handler calls.
