Export prop types consistently across components (<Name>Props)

Summary

Roughly half of sampled components don't export their prop type, so consumers can't import and extend it (e.g. to build a typed wrapper). Coverage is inconsistent even among the most-used components.

Current state

Exported: SwitchProps (switch.tsx:19), AccordionRootProps (accordion-root.tsx:27), DialogContentProps (dialog-content.tsx:8), FieldProps (field-root.tsx:9), FieldsetProps (fieldset.tsx:5), IconButtonProps (icon-button.tsx:20), SelectTriggerProps (select-trigger.tsx:36).

Not exported: ButtonProps (button.tsx:127, plain type, no export), CheckboxGroupProps/CheckboxItemProps (checkbox.tsx:61,88, plain interface), TabsRootProps/TabsTabProps (tabs.tsx:25,55).

Native-attribute extension itself is consistent (125 ComponentProps<...> usages across 74 files) — this is purely about the export keyword being missing on the type/interface declaration.

Suggested approach

• Add export to every <ComponentName>Props type/interface, starting with Button, Checkbox, and Tabs since they're the highest-traffic components.
• Consider a lint rule (or a codemod + CI check) that flags a component file whose prop type isn't exported, so this doesn't regress on new components.

Notes

Found via a components.build practices audit (types dimension).

Start with the declarations in button.tsx, checkbox.tsx, and tabs.tsx, then search the component files for other Props types or interfaces lacking export. Confirm that the affected prop types can be imported by consumers and that the existing component checks still pass; lint or codemod work is optional follow-up.
