* Add start:http and start:stdio npm scripts to examples

For the 6 examples supporting --stdio transport, add explicit scripts:
- serve:http / serve:stdio for running the server
- start:http / start:stdio for build + serve
- start now aliases to start:http for backward compatibility

Update READMEs to document both transport options.
