fix(editor): ship type declarations instead of raw source

@pascal-app/editor exposed only its .tsx source via
exports["."] = "./src/index.tsx", so every TypeScript consumer
type-checked the editor's whole source tree — surfacing the internal
R3F JSX augmentation (declare module 'react/jsx-runtime' in
box-select-tool.tsx), which conflicts with React 19 DOM element types
and pollutes the global JSX.IntrinsicElements union downstream.

Emit declaration-only output to dist/ (tsc -p tsconfig.build.json) and
point the `types` export condition at dist/index.d.ts; runtime stays on
src for embedders' bundlers. Consumers now resolve the public type
surface — the augmentation lives only in box-select-tool's declaration,
which nothing in the public type graph imports, so it stops leaking.

+Ship type declarations and resolve them via a `types` export condition.
+
+`@pascal-app/editor` previously exposed only its raw `.tsx` source
+(`exports["."] = "./src/index.tsx"`), so every TypeScript consumer
+type-checked the editor's entire source tree. That surfaced the editor's
+internal R3F JSX augmentation (`declare module 'react/jsx-runtime'` in
+`box-select-tool.tsx`) inside consumers' programs, where it both conflicted
+with React 19's DOM element types and polluted the global
+`JSX.IntrinsicElements` union.
+
+The package now emits declarations to `dist/` (`tsc -p tsconfig.build.json`,
+declaration-only — runtime is still served from `src` for embedders' bundlers)
+and points the `types` export condition at `dist/index.d.ts`. Consumers now
+resolve the editor's public type surface instead of its source; the internal
+augmentation lives only in `box-select-tool`'s declaration, which nothing in
+the public type graph imports, so it no longer leaks downstream.
