fix(react-start-rsc): re-export renderable types from public entries

[dake3601]

Issue

renderServerComponent returns Promise<RenderableServerComponentBuilder<TNode>>,
but RenderableServerComponentBuilder isn't re-exported from the public entries.

Using declaration: true hits TS2742:

  > The inferred type of 'getChatHistory' cannot be named without a reference
  > to '.../ServerComponentTypes'. This is likely not portable.

Fix

Re-export RendaleServerComponent types.

Summary by CodeRabbit

• Type System Improvements
  • Expanded exported server-component type definitions across package entry points, making richer TypeScript declarations available. This improves editor tooling and type-checking and reduces the need for ad-hoc type workarounds when using server-component APIs.
