### Feature Request / Improvement ### Current Behavior [ManifestEvaluator](https://github.com/apache/iceberg/blob/main/api/src/main/java/org/apache/iceberg/expressions/ManifestEvaluator.java) does not prune manifests for `NOT IN` and `!=` predicates, even when the manifest contains a single distinct partition value where `lower == upper`. ### Proposed Solution When `lower == upper` and the manifest has no nulls or NaNs, we can safely prune: * For `NOT IN`: if the single partition value is in the exclusion list * For `!=`: if the single partition value equals the literal This mirrors the optimization added in #14593 for [InclusiveMetricsEvaluator](https://github.com/apache/iceberg/blob/main/api/src/main/java/org/apache/iceberg/expressions/InclusiveMetricsEvaluator.java), but applied at the manifest level. ### Query engine None ### Willingness to contribute - [x] I can contribute this improvement/feature independently - [ ] I would be willing to contribute this improvement/feature with guidance from the Iceberg community - [ ] I cannot contribute this improvement/feature at this time -- This is an automated message from the Apache Git Service.
