xtask — crate card

Reverse-engineered (from source — verify, don't trust the name)

• One-line pitch: The knut workspace task runner — a publish = false cargo-xtask crate that is the home of the nornir benchmark suite.
• Does: src/main.rs is a thin stub that just prints a hint; the real content is examples/nornir-bench.rs (the nornir bench suite), also wired as a [[bench]] (benches/nornir.rs, harness = false) so cargo bench -p xtask runs the same suite as nornir bench run, emitting nornir's BenchRun JSON. Feature skade adds two benchers: knut.skade_iceberg_export (graph→Iceberg / fast_append) and knut.delta_ingest (Iceberg→FalkorDB delta-vs-full ingest).
• Key deps: anyhow; dev-deps nornir (bench harness), graphar, graphar-falkordb, knut-bifrost, arrow-array/arrow-schema, serde_json, tokio, async-trait, tempfile; feature-gated optional graphar-flight + skade for the Iceberg benchers.
• Shape: bin (+ bench + example); small. src/main.rs (stub), benches/nornir.rs, examples/nornir-bench.rs.
• Observed role in the workspace: The benchmarking/task entry point across the whole workspace; exercises graphar, graphar-falkordb, knut-bifrost and (with skade) graphar-flight, feeding nornir's bench tooling.

• Why it exists (vs the obvious alternative):
• Hard constraint (airgap / no-C-deps / no-FFI / pure-Rust / etc.):
• Release cadence & independence (rides a parent? own repo someday?):
• Status (production / prototype / experimental / stubbed):
• Must-NOT-change invariant:
• Biggest known gap or TODO:
• Anything a newcomer would get wrong about it:
