TankAir Core

# TankAir Core 0.6.0

## Added
- Dense FE Cable (higher transfer rate)
- Wireless Transmitter / Receiver GUI (channel +/-)
- Panel Unifier with Unify button + FE preview
- TankAir Guide book item
- FE Gauge tool
- Modules T4 for all kinds
- Server config: wireless + cable rates

## Fixed / Improved
- Combiner GUI layout (status text no longer overlaps modules)
- GUI atlases 256×256 with clearer slots
- Cable models and industrial textures
- Energy Bank shows stored FE text

## Notes
- Client and server must use the same jar version
- Restart the game after updating (resource reload alone is not enough for new blocks)
