[Docs] Fix TooltipProvider missing from Tooltip API Reference section

[pedromenezes1]

Fixes the Tooltip component's API Reference section, which was missing TooltipProvider and its props (delay, closeDelay, timeout).

Adds a new SUB_COMPONENT_OVERRIDES map to the component-registry codegen so sub-components can be registered for documentation purposes without any runtime change to the component source. TooltipProvider remains a sibling named export.

I've reviewed all the changes in PR #440. Here's my analysis:

Summary of Changes

This PR fixes the Tooltip component's API Reference section by adding TooltipProvider and its props (delay, closeDelay, timeout).

Key Changes:

1. metadata.ts: Added a new SUB_COMPONENT_OVERRIDES map that allows sub-components to be registered for documentation purposes without changing the runtime component structure. This is a clean approach for sibling named exports like TooltipProvider.

2. index.ts: Modified the component processing logic to merge SUB_COMPONENT_OVERRIDES with auto-detected sub-components. The implementation correctly ensures detected entries take precedence over overrides (preventing masking of source-level patterns).

3. tooltip.mdx: Updated the documentation to include the TooltipProvider API reference section using <PropsTable component="Tooltip.Provider" />.

4. index.test.ts: Added comprehensive tests for the new SUB_COMPONENT_OVERRIDES functionality, ensuring the Tooltip.Provider entry is properly configured as a pass-through to TooltipBase.Provider.

5. Changeset: Added a patch changeset for @cloudflare/kumo.

Review Assessment

The changes are well-structured and follow the existing codebase patterns. The approach of using an override map is clean and allows documentation for sibling named exports without requiring runtime changes to the component.

✅ Approved

The implementation correctly:

• Registers TooltipProvider as a sub-component of Tooltip in the registry
• Pulls props from the existing PASSTHROUGH_COMPONENT_DOCS["TooltipBase.Provider"] documentation
• Maintains backward compatibility (detected sub-components take precedence)
• Includes appropriate tests
• Updates the documentation page
• Includes a changeset
