The sync workflow cloned the GitHub mirror into `./gh-mirror` (under the source
checkout), then rsync `./` -> `gh-mirror/` swept the `gh-mirror` directory back
into the destination, polluting the public mirror with a `gh-mirror/` subtree.
Clone to `${RUNNER_TEMP:-/tmp}/awc-gh-mirror` instead, and add a belt-and-suspenders
`--exclude='gh-mirror/'` so a future re-use of the old name can't recur. The next
sync will, via rsync --delete, also remove the polluted directory from GitHub.
