What does this PR do?

Updates GitHub Actions workflows and community health files to formalize the GitFlow branching model and improve project governance.

• Adds gitflow-release.yml to auto-tag and open back-merge PRs after release/hotfix merges
• Adds CODE_OF_CONDUCT.md (Contributor Covenant 2.1) and SECURITY.md (private vulnerability reporting)
• Adds README status badges (CI, release, demo, Hugo version, license)
• Refactors ci.yaml, labeler.yml, release.yaml, stale.yml, and welcome.yml
• Removes label-issues.yml (superseded by labeler.yml)
• Updates CHANGELOG for v0.1.2

Notes for reviewers

gitflow-release.yml requires contents: write and pull-requests: write permissions on the GITHUB_TOKEN. The back-merge PR is opened
automatically and set to auto-merge (--merge) so no manual action is needed after a release lands on master.
