Pull request overview

Prepares the tree/focus plumbing for upcoming overlay work by centralizing workspace focus behavior, tightening workspace teardown cleanup, and avoiding invalid output-name emission for dummy outputs in tree queries.

Changes:

• Added WorkspaceNode::do_focus helper and refactored multiple callers to use it instead of WorkspaceNode::node_do_focus.
• Ensured workspace teardown cleans up seat-related state via seat_state.destroy_node(...).
• Updated jay_tree_query workspace visiting to skip sending an output name for dummy outputs.
