Max FPS booster for fabric

[1.1.1] - 2026-10-24

• Fix a settings-screen crash caused by requesting background blur twice in one frame.

• Target the stable Minecraft 26.3 release with Fabric API 0.161.0+26.3 and Java 25.

• Recover malformed configurations with backups; validate enum, numeric and legacy color values.

• Save configurations atomically where supported.

• Apply HUD scale; track real FPS minima/maxima and reset statistics across worlds and hidden HUD intervals.

• Keep optional debug-cache cleanup on the client thread without forced garbage collection.

• Add configuration and frame-statistic regression tests; remove machine-specific JDK paths and unverified performance claims.
