Limit stroke and shadow effects to default-foreground terminal text so
ANSI-colored output keeps its intended visual meaning.
Also enable terminal text stroke and shadow by default in frontend and
backend fallbacks, and align the dark preset and default xterm theme
with the new green night palette.
Rework the default /workspace layout into a three-column view
with a left-side Workbench, centered terminal, and right-side
status monitor.
Add a new Workbench pane that groups file manager, command
history, and editor into tabs while preserving panel state.
Extend server status data to expose cumulative network upload
and download totals since boot, and show them in the monitor.
Include a lightweight migration for the old default layout and
update related locale strings, pane metadata, and knowledge
base records.
