Unify the four pseudo-element indicator recipes — context-menu and
dropdown-menu × {checkbox-item, radio-item} — into a single partial at
`lib/menu-indicator.css`. The four selectors paint identical geometry
(0.875rem rounded square or circle at the leading inset) so a single
source keeps them in lockstep.
Tokens are exposed as private vars (`--_menu-indicator-{size,radius,
color,inset,mask}`) so a consumer can override per-component without
re-implementing the recipe.
Import order matters: the partial must load AFTER the menu recipes so
its `padding-inline-start: calc(...)` wins over the row rule's
`padding-inline` shorthand at equal specificity. Verified in browser
on both /uix/components/dropdown-menu and /uix/components/context-menu:
checked checkbox-items render 14×14 purple rounded squares, radio-items
render circles, and all rows reserve the same 26px slot so toggling
state doesn't shift text.
Out of scope: Checkbox / RadioGroup / Select.ItemIndicator — those use
`[data-*-indicator]` DOM parts with SVG markers and xs/sm/md/lg/xl size
scales, an architecturally different pattern.
