Delete Snippet

Steps

1. Resolve $DATA_ROOT. Validate $DATA_ROOT/snippets/<category>/<name>.md exists.
2. If config.json.active_layers[<category>] == <name>, refuse unless the user confirms a force-delete. Offer to clear that category from active_layers first (and re-run apply-layers to rebuild the block without it).
3. Confirm by showing description and first few lines of body.
4. Delete the file.
5. If $DATA_ROOT/snippets/<category>/ is now empty, remove the directory.
6. If active and force-deleted, drop the category key from active_layers.
