- .github/workflows/release.yml: on tag push, build exe via ps2exe, package portable zip, attach SHA-256, create GitHub Release. - CHANGELOG.md: Keep a Changelog format, semver. - .github/ISSUE_TEMPLATE/: bug_report.yml + feature_request.yml + config.yml routing security reports to private advisories.
