Add typed radio command form fields with docs, stories, and CI test fixes

[Copilot]

Summary

Adds typed radio field support to CommandForm, including documentation and Storybook coverage for the new field types, and fixes the JavaScript CI regressions uncovered during review.

Added

• Added RadioButtonField and RadioGroupField for CommandForm property bindings (Add Radio button / Radio button groups as command fields #2228)
• Added typecheck coverage to verify radio values stay aligned with the selected command property type (Add Radio button / Radio button groups as command fields #2228)
• Added CommandForm field-type documentation pages for RadioButtonField and RadioGroupField (Add Radio button / Radio button groups as command fields #2228)
• Added a Storybook RadioFields example covering both radio field variants (Add Radio button / Radio button groups as command fields #2228)

Changed

• Exported radio fields from the CommandForm field surface (Add Radio button / Radio button groups as command fields #2228)
• Updated field wrapper keying so multiple radio inputs can bind to the same property without React key collisions (Add Radio button / Radio button groups as command fields #2228)
• Updated CommandForm field-type documentation navigation and related links to include the new radio field pages (Add Radio button / Radio button groups as command fields #2228)
• Isolated useChangeStream test fakes per spec file so the full Arc.React JavaScript CI run no longer shares observable query state across tests (Add Radio button / Radio button groups as command fields #2228)

<RadioGroupField
    value={(c: MyCommand) => c.role}
    options={[
        { value: 'Reader', label: 'Reader' },
        { value: 'Admin', label: 'Admin' }
    ]}
/>

Fixed

• Fixed radio field binding so setValue and option values are inferred from the accessor return type (Add Radio button / Radio button groups as command fields #2228)
• Fixed JavaScript build regressions in queries/for_useChangeStream/* caused by shared fake observable query state during the full workspace CI run (Add Radio button / Radio button groups as command fields #2228)

Removed

• None

Security

• None

Deprecated

• None

@copilot Add documentation and Storybook stories for the new field type

Added the CommandForm field docs for RadioButtonField and RadioGroupField, wired them into the field-types TOC, and added a RadioFields Storybook story in commit 394be01. Screenshot of the built Storybook story: /tmp/radio-fields-storybook.png.

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• example.com
  • Triggering command: /usr/local/bin/node /usr/local/bin/node /home/REDACTED/work/Arc/Arc/node_modules/vitest/vitest.mjs run commands/CommandForm (dns block)
• storybook.js.org
  • Triggering command: /usr/local/bin/node /usr/local/bin/node /home/REDACTED/work/Arc/Arc/node_modules/storybook/dist/bin/dispatcher.js build (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot We're seeing some serious regressions in the JavaScript build that has to be fixed

Fixed in 7dce771. The JavaScript build failure was coming from queries/for_useChangeStream/* tests sharing a fake observable query across files during the full Arc.React CI run, so I isolated those test fakes per file and kept the callback setup deterministic. I re-ran yarn workspace @cratis/arc.react ci successfully. No UI changed in this fix, so there isn’t a new screenshot to attach.
