Run walltime and memory benchmarks on CodSpeed’s ARM64 Graviton runner. Use https://github.com/x52dev/httpea/blob/main/.github/workflows/benchmark.yml as a reference while retaining memory measurements.

Keep the 10-minute job timeout and one-second minimum and maximum sampling times. Let Divan tune sample sizes per benchmark instead of fixing each sample at 10,000 iterations. Divan checks its time budget between samples.

Use actions/checkout@v7.0.1 and update the Actions lockfile. Run on pushes to main and default pull request events; remove the manual workflow trigger. Retain the locked Cargo build and repository action versions.

Validation on 8393620: all 15 checks passed. Walltime and memory measurements completed and uploaded. The benchmark job took 8m 00s (build: 4m 33s; measurement action: 2m 30s). The next slowest job, Rust analysis, took 4m 16s. The benchmark job was 1.875 times as long, within the two-times limit of 8m 32s. This confirms the target for this run; future cache and runner conditions can change the ratio.

Prettier passed for the benchmark workflow. Actions lockfile coverage was verified for all five workflows.
