feat: improve Telegram notifications with direct download links

- Split notifications into build and release
- Release notifications now include:
  - Direct APK download link (clickable)
  - GitHub release page link
  - Feature highlights
  - HTML formatting for better readability
  - Links to @overgramchat
  - Developer attribution
- Build notifications are minimal (non-release commits)
- Automatic posting when new releases are created
- Users can download directly from Telegram message

This means when you create a release (tag), the bot will automatically
post to @overgramupdates with a direct download link!
