Summary

• Enforce the inclusive [0, 1] range in BlendableAction.setWeight.
• Reject NaN and infinities without changing the current value, and apply the same NaN-safe range check to setMaxTransitionWeight.
• Add regression coverage for both endpoints and invalid inputs.

Closes #2025

Validation

• :jme3-core:test --tests com.jme3.anim.tween.action.BlendableActionWeightTest --no-daemon
• :jme3-core:test --no-daemon
• :jme3-core:check --no-daemon (passed; reports existing Checkstyle warnings in unrelated files)
• git diff --check

Thanks for tackling this validation gap. The change keeps the existing setter behavior for valid values while making the allowed range explicit for both blend weight and maximum transition weight.

I reviewed the range checks and the regression tests. The negated inclusive comparisons correctly reject NaN as well as values below zero, above one, and either infinity; because both setters validate before assigning, rejected inputs leave the prior value untouched. The tests cover both endpoints and representative invalid inputs for each setter, including that unchanged-value behavior.

Looks good to me—thanks for including focused coverage for the edge cases.

@riccardobl @yaRnMcDonuts Could one of you review this change for #2025? It validates BlendableAction weight bounds and adds regression coverage; :jme3-core:check passes.
