fix(client): update eventsource-parser for large SSE responses

[Sthreal]

Summary

Update the shared eventsource-parser catalog entry to ^3.0.8, which includes the upstream fix for excessive memory retention while processing large SSE responses.

This updates @modelcontextprotocol/client to eventsource-parser@3.0.8; eventsource@3.0.7 now also resolves its parser dependency to 3.0.8.

Closes #771.
