fix: address PR review issues for auto-mode refactor

- agent-executor: move executeQuery into try block for proper heartbeat cleanup,
  re-parse tasks when edited plan is approved
- auto-loop-coordinator: handle feature execution failures with proper logging
  and failure tracking, support backward-compatible method signatures
- facade: delegate getActiveAutoLoopProjects/Worktrees to coordinator,
  always create own AutoLoopCoordinator (not shared), pass projectPath
  to approval methods and branchName to failure tracking
- global-service: document shared autoLoopCoordinator is for monitoring only
- execution-types: fix ExecuteFeatureFn type to match implementation
- feature-state-manager: use readJsonWithRecovery for loadFeature
- pipeline-orchestrator: add defensive null check and try/catch for
  merge response parsing
- plan-approval-service: use project-scoped keys to prevent cross-project
  collisions, maintain backward compatibility for featureId-only lookups
