NOT IN and != predicates do not prune files when min == max

[joyhaldar]

Feature Request / Improvement

Current Behavior

InclusiveMetricsEvaluator does not prune files for NOT IN and != predicates, even when the file contains a single distinct value where min == max.

Proposed Solution

When min == max and the file has no nulls, we can safely prune:

• For NOT IN: if the single value is in the exclusion list
• For !=: if the single value equals the literal
