fix: resolve CI failures across all platforms

- Fix TS error: use kanbanTaskState?.reviewer instead of task.reviewer
  (reviewer exists on KanbanTaskState, not TeamTask)
- Fix crossTeam tests: update assertions to match XML tag protocol format
  (CROSS_TEAM_PREFIX_TAG → CROSS_TEAM_TAG_NAME with XML attributes)
- Fix controller test: use 'bob' instead of 'alice' as commenter
  (alice is the lead = same as task owner, so no notification fires)
- Fix TeamMcpConfigBuilder test: use path.join() for cross-platform paths
  (forward slashes fail on Windows where path.join uses backslashes)
- Fix atomicWrite EPERM on Windows: add retry logic for rename operations
  (Windows CI antivirus can briefly hold files, causing EPERM on rename)
