Fix primitive array rotations at Integer.MIN_VALUE - #8807

The primitive array rotate methods negate the distance before reducing it modulo the range length. Negating Integer.MIN_VALUE overflows, so rotating {1, 2, 3} by that distance produces {2, 3, 1} instead of {3, 1, 2}, unlike the documented Collections.rotate equivalent.

Reduce the distance modulo the range length before negating it in all eight primitive implementations. Add regression coverage for both whole-array and indexed rotations in each existing test class. No public API changes.

Validation:

• An isolated OpenJDK 17 probe using the current source rotate/reverse methods and equivalent precondition checks compared 65,280 cases with Collections.rotate: eight primitive types, lengths 0–15, every subrange, and ten distances including Integer.MIN_VALUE, its next value, and Integer.MAX_VALUE. The original code had 2,728 mismatches; the fix had none.
• All sixteen changed files were read back and checked against the intended changes.
• The complete Guava Maven/JUnit suite has not been run locally. GitHub Actions validation is pending.
