Function apply_delete

atomic-core/src/crdt/apply/trunk.rs:159–187

Applies a Delete operation to mark a file as deleted. # Behavior 1. Verifies the trunk exists 2. Verifies the trunk is not already deleted 3. Updates the trunk's state to Deleted Note: The trunk entry remains in the database (tombstone). Associated branches and leaves are not automatically deleted. # Errors - `TrunkNotFound` - The trunk doesn't exist - `InvalidTrunkState` - The trunk is alrea
