Pull request overview

Ports the v1 JSDoc documentation for the server function/action serialization mode into the SolidStartOptions config type so downstream tooling/IDE hints can expose the option details.

Changes:

• Added a JSDoc block describing the serialization.mode option and its tradeoffs ("js" vs "json"), including the default.
