ci: free bloat for MSRV job
The MSRV job is running out of memory in CI due to a recent change to
Github's underlying runner. Sounds like this will be resolved at
some point in the future, https://github.com/actions/runner-images/issues/13315,
but until then remove the extra bloat.
What changed, and why it matters
This commit only changes the project's automated CI (continuous integration) workflow. It adds a step to free up disk space on GitHub's virtual machines before compiling the code with the Minimum Supported Rust Version (MSRV). There is no change to the actual Rust Bitcoin library code, no user-facing behavior change, and no security issue.
No security action required. Reviewers may optionally verify the pinned commit hash of the third-party action and confirm it only removes preinstalled packages, but this is a routine CI maintenance change.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The patch adds a ‘Free disk space’ step to the MSRV job in .github/workflows/rust.yml. It uses a third-party GitHub Action (endersonmenezes/free-disk-space@v3.0.0) to remove Android, .NET, and Haskell toolchains from the runner. This is a response to GitHub runner image bloat causing out-of-memory/disk issues during MSRV builds. The change is purely CI infrastructure and does not touch any source code, dependencies, or build outputs consumed by users.
