This PR will make it so that the react sdk build will not cannibalize itself due to having multiple bundle builds that declare clean.

Instead, we will manually clean the dist directory before running the full build.

Note

Overview
Fixes a build race where parallel tsup configs could delete each other’s output in dist, which could leave ./fetch-eventsource type declarations missing after a build.

The build script now runs rm -rf dist before tsup, and clean is removed from all tsup configs (with a comment explaining that a config with clean: true can wipe declaration files while other entry builds are still running).
