6.3.1

Notes:

• For now this only works on 1.21.4, will work on a 1.21-1.21.3 release
• Focused on config stability and debug improvements.

Changes:

• Config values are now validated (invalid configs reset to safe defaults).
• Invalid configs are dumped for debugging.
• Debug overlay shows average visual speedometer creation time.
• Config menu now uses a slider for image size (with proper bounds).

Fixes:

• Prevents crashes and misbehavior from corrupted configs.
• Fixed language strings for size errors (EN & SV).
