[PR] [core] Fix default NOT IN composition in file index reader [paimon]
lilei1128 opened a new pull request, #9612:
URL: https://github.com/apache/paimon/pull/9612
### Purpose
The default FileIndexReader implementation incorrectly combines
multiple NOT EQUAL results with OR when evaluating NOT IN.
Use AND to match SQL semantics:
`a NOT IN (1, 2) = a != 1 AND a != 2`
### Tests
FileIndexReaderTest#testNotInCombinesNotEqualResultsWithAnd
