Commit Message

Fix race detector failures in parallel workflow tests (#2614)

Replace wall-clock timing with sequence number tracking to eliminate
intermittent test failures under race detector.

The race detector adds significant instrumentation overhead that can
cause timing-based assertions to fail. This change addresses the root
cause by using atomic sequence counters to verify execution order
instead of relying on wall-clock time comparisons.

Changes:
- Use atomic.Int64 sequence counters instead of time.Time timestamps
- Move atomic operations outside mutex critical sections
- Add defensive map existence checks with require.Contains/require.Len
- Increase timeout multipliers to 2.5x expected time with clear comments
- Improve error messages to include sequence numbers for debugging

Testing:
All tests now pass consistently under race detector:
- go test ./pkg/vmcp/composer -race -count=50

Fixes #2613
