chore: 🤖 remove leaked radix ui types

[punkbit]

Why?

Introduces click-ui's own DialogProps and DialogTriggerProps types, replacing direct Radix UI type re-exports (leaks). This decouples the public API from internal implementation details.

⚠️ WARNING: Depends on #845 which should be merged first
🤖 On #845 merge, change base branch to main

How?

• Create custom click ui types
• Export old leaks as deprecated

Code Review

Nice work decoupling the public API from Radix UI internals! The approach is solid. There's one build-breaking bug to fix before merge.

---

🚨 Must Fix

• src/index.ts — Duplicate exports: linkStyles and StyledLinkProps are exported twice (lines 300–307 and again 352–359). This will cause a TypeScript compilation error (Duplicate identifier). The second "Deprecated Exports" block at the bottom of the file is a copy-paste artifact and should be removed. Fix this →

---

⚠️ Potential Type Mismatch

• FlyoutContentProps — onPointerDownOutside / onFocusOutside typed as CustomEvent: These are typed as (event: CustomEvent) => void in Flyout.types.ts, but they get spread via ...props into FlyoutContent (a styled(RadixDialog.Content)), which expects Radix-specific event types (PointerDownOutsideEvent, FocusOutsideEvent). With strictFunctionTypes, this may produce a TypeScript error. Consider either using any / Radix's types directly, or handling these in the component (like onInteractOutside) rather than forwarding them.

---

💡 Suggestions (non-blocking)

• FlyoutHeaderProps / FlyoutFooterProps type discrepancy: Flyout.tsx defines and exports richer versions of these types (the union type TitleHeaderProps | ChildrenHeaderProps for FlyoutHeaderProps, and an Omit<ContainerProps<'div'>, ...> extension for FlyoutFooterProps), but Flyout/index.ts re-exports the simpler versions from Flyout.types.ts. Consumers end up with incomplete types. This is pre-existing, but this PR would be a good opportunity to consolidate — move the richer definitions to Flyout.types.ts. Fix this →

• DialogContentProps still extends Radix's type: DialogContentProps in Dialog.types.ts still extends RadixDialog.DialogContentProps. Keeping it in scope for a follow-up is fine, just worth tracking as the next step in this cleanup.

---

The ThemeName narrowing improvement ((typeof THEMES)[keyof typeof THEMES] instead of a hardcoded union) is a nice bonus. 🙌
