Adds idempotent macOS DNS override installer for archive.today and mirrors, plus GitHub Actions workflows for CI and automated mirror list maintenance. - install.sh: idempotent script that writes /etc/resolver files (primary resolver + symlinks), tracks managed entries via manifest, removes stale entries, flushes DNS cache. Supports --update-mirrors (fetches live mirror list from Wikipedia API, no root needed), --dry-run, --uninstall, --no-fetch, --nameserver, --yes. - mirrors.txt: domain list sourced from Wikipedia; first entry is the primary (gets a resolver file), rest become symlinks to it. - .github/workflows/ci.yml: ShellCheck lint, bash syntax check, mirrors.txt format validation on every push/PR. - .github/workflows/release.yml: creates GitHub release on vX.Y.Z tags; verifies tag matches SCRIPT_VERSION in install.sh. - .github/workflows/update-mirrors.yml: runs first Monday of each month, diffs Wikipedia mirror list against mirrors.txt, opens a PR if the set has changed.

DIFF_SUMMARY was computed in the 'Create pull request' step by diffing mirrors.txt against /tmp/ordered_domains.txt — but mirrors.txt had already been overwritten with the new content, so the diff was always empty and the PR body always read 'See diff'. Fix: capture the diff as a step output in the 'check' step (before the overwrite), then reference it via steps.check.outputs.diff_summary in the 'Create pull request' step.

export on a bash array only serialises element [0] to child processes;
relying on an implicit global inside a $() subshell is fragile and
misleading. Instead, pass both arrays as positional arguments using a
"--" delimiter, and parse them inside the function.
Also guard against the empty-manifest edge case: when no manifest file
exists yet, "${MANIFEST_DOMAINS[@]:-}" expands to a single empty string,
which was being treated as a domain to remove. Skip empty entries.
