refactor(cli): move watch/unwatch under workspace subcommand

Reduces top-level command clutter by nesting watch/unwatch as workspace
subcommands. Removes redundant `watches` command since `workspace list`
already shows watched status.

 The daemon monitors one or more workspaces for tasks. Manage which workspaces are watched:
 
 ```bash
-multica watch <workspace-id>    # Add a workspace to the watch list
-multica unwatch <workspace-id>  # Remove a workspace from the watch list
-multica watches                 # Show the current watch list

+multica workspace list                    # Show all workspaces (watched ones marked with *)
 ```
 
 The watch list is stored in `~/.multica/config.json`. Changes are picked up by a running daemon within 5 seconds (hot-reload).
