fix: surface mapStateToProps errors in connect

[louzhedong]

This makes connect rethrow subscription callback errors during render so mapStateToProps failures can reach an error boundary instead of being swallowed.

Quick follow-up in case this is easier to review now than the other connect PR:

This change is intentionally narrow. It only re-surfaces mapStateToProps subscription errors during render so existing error boundaries can catch them, without changing the successful update path.

If you'd prefer this handled in a different layer of connect, or want the regression coverage trimmed to a smaller repro, I'm happy to adjust.
