Search (PQL DSL query) is now the default left tab; Markdown (filtered
to .md files) on the right. Clicking a markdown file publishes on
the message bus; the markdown extension activates the context panel
viewer and re-publishes on a load channel after the frame so the
viewer is guaranteed to be mounted. Viewer subscribes to load channel
and editor buffer events, publishes focus for sidebar highlighting.
