fix(commands): Add missing context parameters to dependency and remove-subtask commands

- Add projectRoot and tag context to all dependency commands
- Add projectRoot and tag context to remove-subtask command
- Add --tag option to remove-subtask command
- Fixes critical bug where remove-subtask was deleting other tags due to missing context
- All dependency and subtask commands now properly handle tagged task lists
