feat: add PruneReader for optimized row filtering (#4370)

* Add PruneReader for optimized row filtering and error handling

 - Introduced `PruneReader` to replace `RowGroupReader` for optimized row filtering.

* Commit Message:

 Make ReaderMetrics fields public for external access

* Add row selection support to SeqScan and FileRange readers

 - Updated `SeqScan::build_part_sources` to accept an optional `TimeSeriesRowSelector`.

* Refactor `scan_region.rs` to remove unnecessary cloning of `series_row_selector`. Enhance `file_range.rs` by adding `select_all` method to check if all rows in a row group are selected, and update the logic in `reader` method to use `LastRowReader` only when all rows are
 selected and no DELETE operations are present.

* Commit Message:

Enhance PruneReader and ParquetReader with reset functionality and metrics handling

Summary:

 • Made Source enum public in prune.rs.

* chore: Update src/mito2/src/sst/parquet/reader.rs
