Add stable extension ID for development builds

Inject manifest key via vite plugin for dev/test builds (not production).
This ensures all developers get the same extension ID: pebbngnfojnignonigcnkdilknapkgid

- Update vite.config.mts to inject key when !PRODUCTION
- Update release script to use PRODUCTION=true
- Replace old hardcoded dev extension ID in all files

extension/vite.config.mts
