Note: a negative delta indicates the PR is faster (an
improvement); a positive delta means the PR is slower (a
regression). Benchmarks are grouped (e.g., small_messages,
spawn_throughput); the flattened list below shows every
individual comparison for clearer deltas.

Benchmarks introduced by the current PR appear only in the pr
column. Once merged, subsequent PRs will compare them against the
main baseline normally.
