restructure pql sidebar: Search default, Markdown tab with viewer

Browse Source 
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.
