v0.0.4

✨ New Features

• Added channel fallback support: each channel can be flagged as a fallback so failed requests automatically retry on backup channels, improving overall availability.
• Surfaced the “use as fallback” toggle directly in the channel edit modal for clearer operation.

🐛 Bug Fixes

• Fixed the fallback toggle not persisting after save.
• Resolved an issue where the edit modal submit button could be blocked under certain states.

📚 Documentation

• Updated README with notes on configuring fallback channels.
