Add 30s request timeouts to SupermemoryClient outbound calls

- Pass explicit timeout: 30_000 to the Supermemory SDK constructor so all
  SDK-backed calls (search, add, forget, profile) are bounded to 30 seconds
- Add AbortSignal.timeout(FETCH_TIMEOUT_MS) to the manual fetch calls in
  getProjects() and getDocuments() which had no timeout before
- Accept an optional { signal?: AbortSignal } argument on both methods so
  callers can thread a request-scoped signal when one is available
- Catch AbortError / TimeoutError in handleError() and surface a friendly
  'Request to Supermemory API timed out' message instead of an opaque crash
- Follow existing codebase convention (FETCH_TIMEOUT_MS constant, same value
  used in apps/api/src/services/extraction/extractors/image.ts)
