Greptile Summary

Pins scikit-learn to <1.8.0 to maintain compatibility with cuml 25.10 in the r.1.1.0 release branch.

• Added scikit-learn<1.8.0 constraint to deduplication_cuda12 optional dependencies (used by GPU-accelerated deduplication features)
• Updated test dependency group from unconstrained scikit-learn to scikit-learn<1.8.0
• Lock file correctly resolves to scikit-learn 1.7.2
• Clear inline comments explain the compatibility constraint

The changes prevent import failures when users install scikit-learn 1.8.0+ alongside cuml 25.10.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The change is a straightforward dependency version constraint that prevents a known incompatibility. The constraint syntax is correct, applied in all relevant places, and the lock file properly resolves to a compatible version (1.7.2). This is a defensive fix with no code changes.
• No files require special attention
