fix(pubsub): Vite build issues

[stocaaro]

Description of changes

Short: This fixes refactors imports to remove all potential for import cycles

Long: Vite uses a different build process that is more sensitive to dependency cycles. In this case, I'm relatively confident that the problem was introduced with how the ConnectionState enum was accessed in ConnectionStateMonitor.ts, however having failed to root out all of the issues once, I've gone through to change the import structure to ensure that there are no import cycles in the package.

Issue #, if available

#10287
#10341

Description of how you validated changes

I have reproduction apps with both React and Vue. For both, I verified the issue before:

• linking in my update package
• removing all vite precomilation artifacts
• restarting the server

rm -rf node_modules/.vite/deps && yarn dev
