* feat(docs): add system theme option to theme toggle
* fix(docs): address review on theme toggle
Render the switcher as a proper radio group (role="radiogroup"/role="radio"
with aria-checked, roving tabindex, and arrow-key navigation) instead of
independent aria-pressed toggles, since the three options are mutually
exclusive. Update the component docstring to describe the three-option
switcher and note that it reads `theme` (not `resolvedTheme`) so the System
option can show as selected. Drop unrelated formatting churn.

Move the live GitHub stars widget into the sidebar footer pill as a
type:"icon" link, sitting opposite the Slack mark (space-between) and
beside the theme switcher. Render it as inner content (GitHub mark +
star + compact count) so fumadocs supplies the anchor.
Replace the default fumadocs theme switcher with a custom two-icon
control where each icon selects its own theme. The built-in
"light-dark" mode is a single blind toggle that flips on any click, so
clicking the sun while already in light mode jumps to dark. useTheme is
sourced from fumadocs-ui/provider/base and the icons are inlined to
avoid bare next-themes / lucide-react imports.
