MemorySnapshotDataTools

Add a new subcommand to the Memory Snapshot Data Tool CLI (the .NET 10 `MemorySnapshotDataTools` exe), wiring it through CliOptions → CommandLineBuilder → Program → a Core runner, then documenting it in README.md. Use when asked to add, create, or expose a new CLI command/subcommand (alongside export, batch-export, report, multi-report, validate, summary, upgrade), or a new flag/argument on an existing one.

Generate and view Unity memory snapshot reports. Use when the user wants to analyze a Unity memory snapshot, export it to a database, validate an export against Unity golden values, or generate/view an HTML report.

Validate a Memory Snapshot Data Tool export against Unity Memory Profiler "golden" values — extract a {name}_golden.json in Unity, export the same .snap to a database, run the `validate` CLI command, and interpret the pass/fail result, tolerances, and failures. Use when asked to validate/verify an export, check it matches Unity's Memory Profiler, produce or read a golden file, debug a validation failure, or change what golden validation compares.

Write and manage SQL queries against an exported Unity memory-snapshot database (DuckDB/SQLite), and keep the schema, views, version, and docs consistent. Use when writing/editing queries over native_objects, native_allocations, native_roots, memory_regions, system_memory_regions, etc.; investigating memory regions; adding or changing tables/views/macros; or checking database version compatibility.

Build, run, screenshot, and test the Memory Snapshot Data Tool — the .NET 10 CLI that exports Unity .snap memory snapshots to DuckDB/SQLite and renders an HTML report. Use when asked to run, start, build, or test the tool, export a snapshot, generate or screenshot a report, or confirm a change works in the real app.
