Memory Benchmarking & Analysis

The perf/memory crate benchmarks memory usage of SQL workloads under WAL and MVCC journal modes. It uses dhat as the global allocator to track every heap allocation, and memory-stats for process-level RSS snapshots.

It also contains a stack-report helper binary for stack-usage investigations. That binary runs a SQL payload with the stacker feature enabled and captures turso_stack tracing events in-process, aggregating structured tracing fields instead of parsing stderr log text.
