Updates to Select

Purely structural — consumer imports and the compound API (<Select>, <Select.Trigger>, <Card.Header>, etc.) are unchanged.

Affected compounds: Accordion, Autocomplete, Breadcrumb, Card, Combobox, Field, Fieldset, RadioGroup, Select, Steps.

Under the hood:

• Root functions renamed from XRoot → X where applicable (internal names only; these were never exported from the package barrel)
• Subcomponent interface X extends Y prop types converted to type X = Y & { ... } for BreadcrumbSeparatorProps, FieldLabelProps, FieldHelperTextProps, FieldErrorTextProps, FieldsetLegendProps, FieldsetHelperTextProps, FieldsetErrorTextProps, RadioGroupLabelProps, RadioGroupHelperTextProps, RadioGroupErrorTextProps, SelectHelperTextProps, SelectErrorTextProps, SelectContentProps
• Root prop types renamed to match convention where previously suffixed with Root (SelectRootProps → SelectProps, ComboboxRootProps → ComboboxProps, AutocompleteRootProps → AutocompleteProps, FieldsetRootProps → FieldsetProps, FieldRootProps → FieldProps, RadioGroupRootProps → RadioGroupProps). The old *RootProps names remain as @deprecated type aliases where they were re-exported from the package barrel (SelectRootProps, ComboboxRootProps, AutocompleteRootProps) for backwards compatibility
• LinkButton / LinkIconButton: inlined CVA variant props (intent, emphasis) as literal unions rather than VariantProps<typeof buttonVariants>['key'], which react-docgen-typescript couldn't drill into. New exported type aliases: LinkButtonIntent, LinkButtonEmphasis, LinkButtonSize, LinkIconButtonSize for consumers who want to annotate their own wrappers
