## What changes were proposed in this pull request? Moves the last hardcoded `TimeType` check out of the vectorized reader into the Types Framework. `VectorizedColumnReader.isLazyDecodingSupported` decided lazy dictionary decoding for TIME columns via the annotation-keyed `ParquetVectorUpdaterFactory.isTimeTypeMatched(MICROS|NANOS)`; it now dispatches framework-first (like `getVectorUpdater`): - `ParquetTypeOps.supportsLazyDictionaryDecoding(descriptor): Boolean` (default `true`) + Java entry point `supportsLazyDictionaryDecodingOrNull` (null for non-framework types). - `TimeTypeParquetOps` overrides it to `false` (its updater does per-value micros→nanos + truncation that lazy decoding would bypass). - `VectorizedColumnReader.isLazyDecodingSupported` dispatches framework-first; the two `isTimeTypeMatched` arms are removed. - Removes the now-dead `ParquetVectorUpdaterFactory.isTimeTypeMatched` and its unused import. ### Why are the changes needed? `isTimeTypeMatched` was the last hardcoded `TimeType` reference in the vectorized path after the updater moved into the framework. The decision also becomes more precise: it now keys on the requested Spark type, so a TIME column read as raw `LongType` (identity copy) is lazy-decodable, whereas the annotation-keyed check disabled it. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? `TimeTypeParquetOpsSuite` (new unit test for the predicate), `ParquetVectorUpdaterSuite`, and `ParquetIOSuite` TIME tests under `withAllParquetReaders` (dict on/off). ### Was this patch authored or co-authored using generative AI tooling?
