50ea6ef: fix: use explicit .js extensions in ESM imports for Node.js compatibility
Switch moduleResolution from bundler to nodenext and add .js extensions to all relative imports. The published packages use "type": "module" but the compiled output had extensionless imports, which breaks Node.js ESM resolution. Also add "type": "module" to @elevenlabs/types.
