RGBTimer

# Changelog 1.7.5

- Added a configurable normal-timer milestone interval: 10, 15, 30, 45, or 60 minutes.
- 60 minutes remains the default; the overlay can still be disabled completely.
- Every naturally reached boundary appears as a large centered overlay for about 3.5 seconds.
- The overlay follows the selected time format: for example `10min`/`1h` or `0:10:00`/`1:00:00`.
- Uses the selected RGB/HEX design with animation, bold text, shadow, outline, and the optional background.
- Can be enabled or disabled in the config; the default is **ON**.
- No false trigger after a world/server switch, restore, reset, or `/timer settime`.
- Digital hours continue beyond 24, for example `25:00:00`.
- Available for all 17 supported Fabric and NeoForge targets.
- Separate world/server storage and the Fabric switching fix from v1.7.3 remain included.
- No features from the withdrawn v1.8.0 and v1.9.0 releases.
