chore: pin GitHub Actions to commit SHAs#105

The previous form `taiki-e/install-action@eb170ab` (with the `parse-changelog` shorthand) pinned to the SHA the moving `parse-changelog` tag in install-action pointed at when Dependabot ran. Since then the tag has moved (now `5fcbcfe`) and `eb170ab` is no longer reachable from any branch or tag in install-action — GitHub's UI shows it as 'This commit does not belong to any branch on this repository'. A dangling object can be garbage-collected and would break the workflow. Pin to a SHA that's reachable from a release tag instead: the canonical install-action form (`@v2.75.4` SHA) plus `tool: parse-changelog@<v0.6.16 SHA>`. Both SHAs are tag-reachable and durable, and Dependabot can track them. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Pin GitHub Actions to commit SHAs
GitHub Actions referenced by tag (e.g.
actions/checkout@v4) use a mutable pointer — the tag owner can move it to a different commit at any time, including a malicious one. This is the attack vector used in the tj-actions/changed-files incident (CVE-2025-30066).Pinning to a full 40-character commit SHA makes the reference immutable. The
# tagcomment preserves human readability so reviewers can tell which version is pinned.Important: a SHA can also originate from a forked repository. A malicious actor can fork an action, push a compromised commit to the fork, and the SHA will resolve — but it won't exist in the upstream canonical repo. Each SHA in this PR was verified against the action's canonical repository (not a fork).
