.github/workflows README understates current PR-time CI

What happened?

.github/workflows/README.md describes the current PR-time CI strategy, but it appears to omit some checks that now run on pull requests.

Examples:

• The README says bazel.yml runs Bazel test and Bazel clippy for Rust code. The workflow also has a PR-triggered verify-release-build job that builds release targets and verifies release behavior such as bwrap.
• The README lists the small Cargo-native rust-ci.yml checks as cargo fmt --check, cargo shear, argument-comment-lint, and argument-comment-lint package tests. The workflow also runs just bench-smoke as a Rust benchmark smoke test.

Expected behavior

The workflow strategy README should list the current PR-time checks, including the release-build verification and benchmark smoke test, so contributors have an accurate picture of what CI will run before merge.

Additional context

I searched open issues and PRs for terms including .github/workflows/README.md, rust-ci, bench-smoke, and verify-release-build, and did not find an existing open item that appears to cover this documentation drift.
