chore(deps): support TypeScript 6 (widen peer to ^5 || ^6)

- Add typescript ^6.0.0 as devDependency for verified builds
- Widen peerDependency to ^5 || ^6 to keep TS 5 consumers supported
- tsconfig.build.json: set explicit rootDir (required by TS 6 when outDir is set)
- tsconfig.build.json: replace deprecated moduleResolution "node" with "bundler"
