1.1.1 improves remote-config reliability and Firefox release readiness.

Changes in this version:
- updated the embedded signed remote-config public key
- improved signed remote-config handling and validation
- strengthened automatic config recovery for Twitch PlaybackAccessToken changes
- aligned config validation with the extension's runtime request shape
- refreshed internal Firefox release packaging and workflow compatibility

This release is intended to improve resilience when Twitch changes playback-related GraphQL configuration.
