NAWS mid-session updates now propagate to the window stack: Application
re-runs each open window's relayout on resize. Window#relayout re-centers
(clamped to the screen edge) by shifting all descendants; MasterDetail
recomputes its full geometry and re-renders the detail at the new width.
ButtonBar placement is extracted into ButtonBar.place for reuse.

Markdown.to_lines now detects GFM tables (header + delimiter row) and
renders them as box-drawn, alignment-aware tables that shrink to fit the
pane width, instead of mangling the rows into a single paragraph.
ScrollView now handles mouse-wheel events, and Window routes wheel
events to the widget under the cursor, so a detail/content pane scrolls
even when keyboard focus is on an adjacent list.
