Document root cause analysis of workflow run #21588949791 failure

[Copilot]

Investigated CI failure in workflow run #21588949791 on branch copilot/expose-embeddings-api (commit e4ed86f). The "Verify formatting" step failed due to Dart formatter violations.

Root Cause

Function signature in lib/src/backend/native/worker.dart violated Dart formatting rules:

// Failed CI:
void _handleEmbeddings(
  EmbeddingsRequest request,
  _LlamaWorkerState state,
) {

// Expected by dart format:
void _handleEmbeddings(EmbeddingsRequest request, _LlamaWorkerState state) {

Investigation Summary

• Retrieved workflow logs showing "Changed lib/src/backend/native/worker.dart" during format check
• Fetched commit e4ed86f and reproduced failure locally with dart format --set-exit-if-changed
• Confirmed exact formatting delta causing CI rejection

This issue was subsequently addressed in PR #26 which has been closed.
