fix(dropdown-menu, context-menu): keep menu open on CheckboxItem / RadioItem activation

Soma's MenuCheckboxItem / MenuRadioItem default `closeOnSelect=true`
(matches Radix Primitives), but for toggle-state items that's the
wrong UX default — the user wants to flip multiple checkboxes or
switch a radio choice without re-opening the menu each time.

Override the default in the eidos wrappers for both DropdownMenu and
ContextMenu (4 components total: CheckboxItem + RadioItem in each).
Activating Item (plain command) still closes by default; only the
state-toggle parts stay open.

Consumers who genuinely want close-on-toggle can pass
`closeOnSelect={true}` explicitly.
