### What problem does this PR solve? File Scanner V2 applies row-level dictionary-ID filtering to non-string Parquet dictionaries. This differs from the V1 and StarRocks strategy, where non-string dictionary values are decoded before filtering, and can bypass the intended logical value domain. ### What is changed? - Restrict row-level dictionary-ID filtering to logical string columns. - Keep non-string dictionaries on the decoded-value reader-direct or residual VExpr path. - Update focused INT/BIGINT/runtime-filter coverage and the V2 Parquet scan design. ### Verification - ASAN BE UT: 68/68 tests passed for ParquetScanTest and ParquetRuntimeFilterDirectReaderTest. - clang-format --dry-run --Werror passed. - git diff --check passed. -- This is an automated message from the Apache Git Service.
