Perf: Native memory allocation and hookDB connection optimization
Two performance improvements:
1. Native memory allocation via mimalloc for hot paths:
- Add encoding/native.go with MarshalNative using mimalloc
- Add encoding/native_stub.go for non-CGO fallback
- Integrate in meta_store_pebble.go hot paths (WriteIntent, BeginTransaction, etc.)
- 75% reduction in Go heap allocations for serialization
2. Fix hookDB connection held too long during CDC processing:
- Release hookDB connection immediately after SQLite rollback
- ProcessCapturedRows now runs after connection release (uses only Pebble)
- Reduces hookDB hold time from seconds (Pebble warmup) to milliseconds
- Fixes initial stall with high concurrency (512 threads)
