Custom Enchants 3.2.5 — Minecraft 1.21.11

This is a targeted Double Jump movement hotfix for Minecraft 1.21.1 and 1.21.11.

Fixed

• Double Jump movement is now predicted immediately on the activation input tick instead of waiting for the full client → server → client round trip.
• Fixed the delayed horizontal/vertical kick that made Double Jump feel jerky on Minecraft 1.21.x.
• Sprint state and activation yaw are now captured at the exact activation moment, preventing the jump impulse from using a later/stale direction.
• Server validation remains authoritative.
• Server approval is acknowledgement-only and no longer applies the same movement impulse a second time after network latency.
• Minecraft 1.21.11 uses its correct hurtMarked movement synchronization path.

Validation

• Final Double Jump behavior was manually verified and accepted on Minecraft 1.21.1 and 1.21.11.
• Unit/contract tests, Gradle check/build, release-JAR verification, Fabric GameTests and dedicated-server smoke tests pass.

Minecraft 1.20.1 is unaffected and remains on version 3.2.4.

No enchantment balance or configuration changes.
