- Fix board display: rejected planning tasks move to Blocked group
- Fix path traversal: review API validated task names against ../ injection
- Fix URL encoding: unquote() task names in API path parsing
- Fix comment parsing: robust REVIEW.md read/write, handle falsy comments
- Fix dead code: KanbanBoard class missing COLUMNS and __init__
- Fix inotify: explicit error messages and polling fallback
- Fix review API: validate task names, prevent path traversal
