Upstream: Hamlib 4.7.2 available (pinned at 4.7.1)

[github-actions]

Automated upstream version check.

• Component: Hamlib
• Pinned: 4.7.1
• Latest upstream 4.x tag: 4.7.2

To bump

Update hamlib_branch in:

• .github/workflows/ci.yml (five jobs)
• .github/workflows/release.yml (five jobs)

Open a PR against develop, let CI run on all five platforms, then merge.

Notes

• This check only tracks the 4.x series. A future Hamlib 4+1 major release would require design review and is intentionally ignored here.
• Close this issue once the bump PR is merged. The next weekly run will re-file if another 4.x release appears.
