Report benchmark test results

[notmike-5]

The benchmarking workflow reports on some performance metrics (see below). However, the benchmark code either does not collect or does not parse the criterion data and report the results.

Performance Comparison

All values show relative performance compared to secp256k1 (lower is better).

Algorithm	Key Generation	Signing	Verification
secp256k1	1.00x	1.00x	1.00x
ML-DSA-44	Needs Update	Needs Update	Needs Update
SLH-DSA-128S	Needs Update	Needs Update	Needs Update

Note: Performance values require parsing Criterion output and are not yet updated automatically.
