The file panels' action verbs (Send/Edit/Rename/new folder/new file/
permissions/Delete) and the panel picker were wearing the full Aero slab,
which is the dialog push-button treatment — wrong for what is really an
Explorer command bar. Marked the session strip w7-toolbar so they get the
flat-with-hover-glow treatment the Connections button already had from the
tab-bar row.
The path bar gets it too. Its up/refresh controls sit directly under the
action row, so leaving them as slabs beside newly-flat neighbours would have
read as arbitrary rather than deliberate. w7-toolbar only targets button, so
the path <input> keeps its 7.css textbox border.
Verified on a live single-instance capture: both rows flat, the path input
unchanged. architecture.md's "three header rows" was now wrong and says
"every command row" instead.
