Replace origin override with global option

- Remove origin parameter from connect() method
- Add ConnectOptions interface with global flag
- When global: true, sends X-Rondevu-Global header instead of trying to override Origin
- Update client methods to accept customHeaders parameter
- Pass custom headers through connection polling and ICE candidate exchange
- Bump version to 0.1.0

This change works around browser restriction on Origin header modification.
