pub fn load_all(root: &Path) -> Result<Vec<(Target, BenchEntry)>>Expand description
2026-09-26: Every benchmark entry in the tree, validated, with the target each belongs to.
Files are found by bench_files, not taxon::walk: the walk needs a
MODEL.toml and a quant directory, and a BENCH.toml may exist before its
model’s kernels do.
