refactor(web): remove unused input component variants

[juliusmarminge]

The input modules carry variants with no callers. Remove unused combobox chips, autocomplete wrappers, select helpers, number-field scrubbing, and other unused input variants.

Remove the NumberField context with its only consumer while preserving root IDs and props. Keep the Combobox chips-ref context and popup anchor behavior; only its unread multiple field is removed.

Layer 2 of 7 in the web runtime-export cleanup stack. Based on #10222.

Verification at the integrated stack tip: vp run --filter @t3tools/web test passes all 4,052 tests across 333 files. Web typecheck and changed-file lint/format pass. The stack passes vp run knip:check, including repository file/dependency checks and runtime-export checks for web and all seven internal packages.

Model: gpt-6 astra. Harness: Codex in T3 Code.

Note

Remove unused input component variants from autocomplete, combobox, and other UI modules

• Strips unused wrapper components and their named exports across seven UI modules, with the largest changes in combobox.tsx and autocomplete.tsx
• In combobox.tsx, drops the multiple field from ComboboxContext and memoizes the provider value with an empty dependency list
• In number-field.tsx, removes NumberFieldContext, NumberFieldScrubArea, and CursorGrowIcon; the field ID is still passed directly to the primitive root
• Removes SelectButton and SelectSeparator from select.tsx, InputGroupText and InputGroupTextarea from input-group.tsx, Radio/RadioGroupItem from radio-group.tsx, and ToggleGroupSeparator from toggle-group.tsx
• Risk: any in-tree or external consumer importing the removed named exports (e.g. ComboboxChips, SelectButton, AutocompleteRow, NumberFieldScrubArea, InputGroupTextarea, Radio) will fail to compile

Approvability

Verdict: Approved at 9d12bd7

Macroscope's review found this PR approvable — This is a deletion-only cleanup of unused internal UI wrappers and exports across seven web component files. Existing in-repository callers and retained component behavior are unchanged, with no product-default, deployment, security, billing, or static-analysis implications identified.

Closing this layer after maintainer review. Core UI component modules are kept as complete pasted component sets, so this partial subcomponent cleanup is intentionally dropped. #10228 now records the matching Knip export exception while retaining whole-file detection.
