* fix: capture exact OpenCode session ID from JSON stream to prevent orphan sessions
- Primary: Extract session_id from opencode run --format json step_start event
- Fallback: Title-based match with newest-first sorting for delayed visibility
- Core: Add atomic reserveSessionId check in spawnOrchestrator to prevent race conditions
- Prevents orphan sessions when multiple spawns use same title or delayed discovery

- Update integration tests to expect --format json flag in launch commands
- Fix assertions for exec opencode --session wrapper format
* fix: address Bugbot findings on PR #366
- Fix orphaned runtime leak when reuse strategy finds alive runtime but
get() returns null (now destroys the orphaned runtime)
- Restore session ID format validation in fallback script with
isValidId regex check
- Add regression tests for both fixes
* fix: address additional Bugbot findings on PR #366
- Add timestamp helper to fallback sort to avoid NaN from invalid dates
- Add session ID type/format validation to primary capture script
