fix: use explicit paths in external array for React outputs

- Replace function matcher with explicit string paths (tsup doesn't support functions)
- List all React output import paths explicitly in external array
- This ensures tsup marks them as external during its resolution phase
- Fixes 'Could not resolve' errors during React build
