Rebuild: edge-bench-rs, the edge worker's indexing in Rust, for comparison

The RangeIndexer path of edge:bench (inflate, scan, owner rule, segments,
file aggregation, cut-off, rules, release identity, chunk encoding v2,
probe candidates) as a Rust binary over a captured range, with JS
semantics where they matter (\s, trim, \b, parseInt, lastIndexOf, UTF-16
lengths). check.ts runs the TypeScript RangeIndexer on the same capture
and compares every output: identical on all three captures (releases and
their decoded payloads, samples, candidates, rule counts, fragments),
after mapping Date headers ending in UTC to GMT (chrono follows RFC
5322; Date.parse takes UTC, a quarter of a.b.boneless). Compressed
payloads differ by <0.1% in size (zstd framing), not in content.

First run on boneless 2026: 360k headers/s and 228 MB peak (TypeScript:
~217k/s, ~0.7-0.8 GB).
