          ## Highlights

          ### Performance: 1 Billion JSON Records in 16 seconds
          - **Parallel group-by**: 1B records at 3.0 GB/s (97% of disk I/O speed)
          - **bjq native** 2-5x faster than jq on all scales
          - 100M+ records with only 4GB heap (jq OOMs at 100M)

          ### New Architecture
          - **FastJSONParser**: byte-level parser with field interning, CompactObject, Int32 cache
          - **StreamingJSONParser**: SIMD structural index, zero-copy slices for >2GB files
          - **MappedJsonScanner**: Foreign Memory API mmap for multi-GB files
          - **ParallelGroupByExec**: 1BRC-inspired parallel chunk processing with open-addressing byte-key hash map
          - **SpillableGroupBy**: disk-spill for large aggregations
          - **MorselPipeline**: DuckDB-inspired morsel-driven parallelism
          - **TupleSerializer**: binary serialization for external merge sort

          ### Native Binaries
          All binaries built with Oracle GraalVM, PGO (Profile-Guided Optimization), G1 GC, and -O3:
          - `bjq-linux-amd64`
          - `bjq-linux-arm64`
          - `bjq-macos-amd64`
          - `bjq-macos-arm64`
          - `bjq-windows-amd64.exe`

          ### Install
          ```bash
          curl -L https://github.com/sirixdb/brackit/releases/latest/download/bjq-linux-amd64 -o bjq
          chmod +x bjq
          sudo mv bjq /usr/local/bin/
          ```
