fix: fetch full git history in release workflow for git-cliff

[robdefeo]

Summary

• The plan job checkout used fetch-depth: 1 (shallow) and fetch-tags: false — git-cliff only saw the single release commit and no tags, producing empty changelog output
• Adding fetch-depth: 0 and fetch-tags: true gives git-cliff the full history it needs

After merging

Delete the v0.1.0 tag/release and re-cut from updated main.

Greptile Summary

This PR fixes an empty changelog issue in the release workflow by giving git-cliff access to full git history and tags. The plan job previously used a shallow clone (fetch-depth: 1, no tags), so git-cliff could only see the single release commit and produced empty output. Adding fetch-depth: 0 and fetch-tags: true resolves this.

• The fix is correctly scoped to the plan job only, which is the job that invokes dist host --steps=create / dist plan and drives changelog generation via git-cliff.
• The other jobs (build-local-artifacts, build-global-artifacts, host, announce) perform builds and artifact uploads and do not need full history, so leaving them as shallow clones is appropriate and avoids unnecessary overhead.
• The change is minimal, targeted, and directly addresses the described root cause.

Confidence Score: 5/5

Safe to merge — the fix is minimal, correct, and scoped precisely to the job that needs full git history.

Two-line addition of well-understood actions/checkout parameters (fetch-depth: 0, fetch-tags: true) applied only to the job that requires them. No logic changes, no new dependencies, and the root cause matches the fix exactly.

No files require special attention.
