Pin all action references to specific commit SHAs to prevent supply-chain attacks. Each pin is annotated with a human-readable version tag for clarity. Versions stay within the existing major version to avoid breaking changes.

Pull request overview
Pins all GitHub Actions uses: references in workflows to specific commit SHAs (with version tag annotations) to mitigate supply-chain risks from tag retargeting.
Changes:
- Replace tag-based action references (e.g.,
@v5) with full commit SHAs and trailing version comments across all workflows. - Pin
SiaFoundation/workflows@masterto a specific SHA snapshot of the master branch. - Update
knope-dev/actionpin from a bare SHA to a SHA annotated with# v2.1.2.

Summary
uses:reference in workflows to a specific commit SHA@v4→ latest v4.x.y SHA) to avoid breaking changesWhy
Mitigates supply-chain attacks where a tag could be retargeted to malicious code. Pinning to a SHA is the recommended hardening practice.
Notes for reviewers
SiaFoundation/workflows@masteranddtolnay/rust-toolchain@stable|nightly(which use a branch ref intentionally), the pin uses the current branch tip SHA — future updates will require a follow-up PR
