feat(select): allow accessible name on standalone Select, Combobox, Autocomplete

[erickteowarang]

Summary

The high-level standalone Select, Combobox, and Autocomplete had no way to receive an accessible name when used outside a Form/FormControl. Passing aria-label, aria-labelledby, or id compiled fine (React allows aria-*/id in JSX typing) but the props were discarded at runtime — the components destructured a fixed prop set and never spread the rest onto the trigger/input. The result was a combobox whose only accessible name was its current value, breaking WCAG 4.1.2 (Name, Role, Value) and 2.5.3 (Label in Name) for table toolbars, list filters, and faceted search.

This implements proposed fix #1 from the issue — adding first-class aria-label / aria-labelledby / id props that forward to the trigger — applied consistently across all three standalone components (including .Async and creatable variants) as the issue recommends.

Changes

• select-standalone.tsx — added aria-label/aria-labelledby/id to SelectPropsBase; forwarded onto SelectTrigger (the combobox-role element) in SelectStandalone and SelectAsyncStandalone, single and multiple modes.
• combobox-standalone.tsx — added the props to ComboboxPropsBase; added an inputProps param to ComboboxShell spread onto ComboboxInput; wired all four paths (static/async × plain/creatable) via a pickInputProps helper, stripping the a11y props from the ...valueProps spread so they don't leak onto ComboboxRoot.
• autocomplete-standalone.tsx — added the props to AutocompletePropsBase; forwarded onto AutocompleteInput in both static and async components.

Usage

// Announced as "Direction filter, combobox" instead of just its value
<Select items={items} value={value} onValueChange={setValue} aria-label="Direction filter" />

// Or point at a visible label
<span id="dir-label">From</span>
<Combobox items={items} aria-labelledby="dir-label" />

Tests & docs

• Added an "accessible name" describe block to each of the three *-standalone.test.tsx files (15 new tests) covering aria-label, aria-labelledby, id, multiple mode, creatable, and async — each asserting getByRole("combobox", { name }) now resolves.
• Updated docs/components/{select,combobox,autocomplete}.md prop tables and Accessibility sections.
• Added a minor changeset.

Verification

• pnpm type-check clean
• pnpm lint — 0 warnings, 0 errors
• pnpm test — 1244 passed

Closes tailor-inc/platform-planning#1455
