fix(tags): Resolve tag deletion bug in remove-task command

Refactored the core 'removeTask' function to be fully tag-aware, preventing data corruption.

- The function now correctly reads the full tagged data structure by prioritizing '_rawTaggedData' instead of operating on a resolved single-tag view.

- All subsequent operations (task removal, dependency cleanup, file writing) now correctly reference the full multi-tag data object, preserving the integrity of 'tasks.json'.

- This resolves the critical bug where removing a task would delete all other tags.
