fix(solid): keep generated declarations private

[brenelz]

Summary

• remove the broad solid-js/types/* package export
• keep TypeScript auto-imports on the supported solid-js entry point instead of emitted client/server declaration modules
• add a package-boundary regression test and release changeset

Context

The wildcard makes every generated declaration module a public auto-import source. In a configured Solid project, TypeScript consequently offers both solid-js and solid-js/types/server/signals.js for createSignal. The latter has no matching runtime file and fails when emitted as a value import.

The wildcard was introduced for Solid 1 internal type consumers. Those old declaration paths are not present in Solid 2, while the supported values and types are exposed from the package root.

Test plan

• pnpm --filter ./packages/signals run build
• pnpm --filter ./packages/solid run types
• pnpm --filter ./packages/solid run test-types
• pnpm --filter ./packages/solid run build
• pnpm --filter ./packages/solid exec vitest run (576 tests)
• verified in a Solid 2 application that the configured-project completion only offers solid-js; its 10 tests and client/SSR Vite build pass
