fix(execute-phase): add Copilot sequential fallback and spot-check completion detection (#1128)
- Default Copilot runtime to sequential inline execution instead of
unreliable subagent spawning
- Add spot-check fallback in step 3 (SUMMARY.md exists + git commits
found) so orchestrator never blocks indefinitely on missing completion
signals
- Add runtime detection guidance in init step to force sequential mode
under Copilot
- Add regression test verifying execute-phase contains Copilot fallback
and spot-check documentation
