feat(react): re-export core utilities as namespaces (closes #2025)

[timagixe]

Summary

Closes #2025.

Adds namespaced re-exports from @dnd-kit/react:

• abstract from @dnd-kit/abstract
• collision from @dnd-kit/collision
• dom from @dnd-kit/dom

This lets React consumers access common lower-level utilities without adding each package as a direct application dependency.

Notes

This is intentionally React-only for the first pass, matching the issue label. The same pattern can be mirrored to other framework adapters if maintainers prefer.

This also keeps the re-exports namespaced rather than using unnamespaced export *, to avoid expanding the React root API with every lower-level export.

Verification

• bun run build in packages/react
• Runtime smoke import for abstract, collision, and dom

Summary

Adds namespaced re-exports abstract, collision, and dom to @dnd-kit/react, so consumers can pull collision detectors, plugins, and types through the React entry point without each @dnd-kit/* package becoming a direct app dependency. Matches the request in #2025.

Feedback

Blocking issues

None.

Suggestions

• packages/react/src/core/index.ts:28 — namespace re-exports rather than export * is the right call. It avoids future name collisions when lower-level packages add new symbols, and consumers still get tree-shaking with modern bundlers. Good judgment in the PR notes on this.
• packages/react/package.json:67 — @dnd-kit/collision is added as a direct dependency. That's appropriate since it's now imported at top level (previously it was reachable only transitively through @dnd-kit/dom).
• packages/react/tsup.config.ts:7 — @dnd-kit/collision correctly added to external so it isn't bundled.
• One thing for the maintainer to weigh: this is a public API surface expansion (the abstract, collision, dom namespace names are now part of the contract). The PR is intentionally React-only for a first pass — if the same pattern lands in @dnd-kit/vue / @dnd-kit/svelte / @dnd-kit/solid later, naming consistency across adapters is worth keeping in mind.

Changeset

• Status: present, minor for @dnd-kit/react. Correct — this is a new public API.

Overall

Clean, minimal change. Thanks for following the user's exact example from #2025 and for the thoughtful note explaining the namespaced approach.
