- MoveToNextColumn: moves task to next column in workflow
- MoveToPreviousColumn: moves task to previous column
- Gets columns sorted by position, finds current, moves to adjacent
- Returns ErrAlreadyInLastColumn when at workflow end
- Returns ErrAlreadyInFirstColumn when at workflow start
- Handles column gaps (non-sequential positions)
- Comprehensive test coverage for all edge cases
- GetTags: retrieve task tags as map[int]string
- SetTags: replace all tags on a task
- ClearTags: remove all tags
- AddTag: read-modify-write, idempotent (no-op if tag exists)
- RemoveTag: read-modify-write, idempotent (no-op if tag doesn't exist)

WARNING: Tag operations are NOT atomic. Concurrent modifications may
cause data loss due to the read-modify-write pattern required by
Kanboard's setTaskTags API.
Comprehensive test coverage including idempotency tests.
