fix: address Sentry review findings from PR #144 (#147)

- Use unique `MessageID`/`SessionID` instead of hardcoded `"enhance-prompt"`
  string for synthetic LLM calls (prevents future API validation breakage)
- Add `enhancingInProgress` guard to manual enhance handler to prevent
  concurrent enhancement race with auto-enhance on submit
- Fix auto-enhance early `return` that orphaned sessions: now uses latest
  user text and continues submission instead of silently abandoning it
