📝 WalkthroughWalkthroughUpdates the GitHub Actions coverage workflow to use the stable Rust toolchain, add llvm-tools-preview, install grcov, enable coverage instrumentation via environment flags, generate an lcov.info with grcov, and upload that report to Codecov; branch trigger formatting and step ordering were also adjusted.

24-25: Use locked dependency resolution forgrcovinstall to improve reproducibility.Line [25] installs whatever is latest at runtime, which can make CI behavior drift.

Verify each finding against the current code and only fix it if needed. In @.github/workflows/codecov.yml around lines 24 - 25, The workflow installs grcov without lockfile, causing non-reproducible CI; update the step that runs the install command (the `cargo install grcov` invocation) to use locked dependency resolution (for example add `--locked`, or better yet pin a specific `--version` plus `--locked`) so Cargo uses the lockfile and the install is reproducible.

In @.github/workflows/codecov.yml:
- Around line 17-23: Update deprecated workflow actions: replace
actions/checkout@v3 with actions/checkout@v4 to avoid Node16 dependency issues,
and replace the archived actions-rs/toolchain@v1 usage with a maintained Rust
setup action (e.g., actions/setup-rust@v1) or the project-preferred maintained
Rust toolchain action; update invocation parameters accordingly so toolchain
installation/override (the previous actions-rs/toolchain behavior) is preserved.
- Around line 47-54: The Codecov upload step ("Upload to Codecov") is unguarded
and will fail for forked PRs when CODECOV_TOKEN is missing due to
fail_ci_if_error: true; modify that step to run only for non-forked contexts by
adding an if condition that checks the event and fork status (e.g., if:
github.event_name != 'pull_request' || github.event.pull_request.head.repo.fork
== false) so the step (which uses codecov/codecov-action@v5 with files:
lcov.info, verbose: true, fail_ci_if_error: true and env CODECOV_TOKEN) is
skipped for forked PRs where the secret is unavailable.
