…edup Replace the pure-JS hash.js SHA-256 implementation with node:crypto's native OpenSSL-backed createHash in the gossipsub message ID function. Benchmarks show this reduces hashing time from ~47ms to ~945us for 1MB messages. Also adds a benchmark test comparing hash.js, node:crypto, crypto.subtle, and xxhash implementations.

Replace aztec/foundation for native sha256. The native sha256 implementations are orders of magnitude faster than hash.js (which is not surprising). I have used the web-crypto subtle.digest since it's async.

Replace hash.js for native sha256 when computing P2P message IDs. Fix A-583 Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>

In #20846 we showed the hash.js's sha256 implementation is very slow on large buffers and we know we're pushing hundreds of KB to megabytes to the broker every seconds, this would speed up proving job ID generation a lot. I have not used the async variant through `crypto.subtle` because ID generation is synchronous. The sync API is much faster than the async but won't be capable of as high throughput.

Replace aztec/foundation for native sha256. The native sha256 implementations are orders of magnitude faster than hash.js (which is not surprising). I have used the web-crypto subtle.digest since it's async.
