Add open-source scaffolding and CI; remove Claude-specific dev notes from the published tree. - Remove CLAUDE.md from tracking (kept locally, now git-ignored). - CHANGELOG.md (Keep a Changelog; v1.0 → v1.1.1). - SECURITY.md (private vuln reporting + operator guidance). - CONTRIBUTING.md (dev setup, conventions, PR flow). - .github/: bug + feature issue templates, PR template. - .github/workflows/ci.yml: byte-compile, validate example config, docker build. - .github/workflows/release.yml: on a version tag, publish a multi-arch (amd64 + arm64) image to GHCR. - README: license/release/CI badges, prebuilt-image (GHCR) run instructions, and a corrected Python-version note (3.9–3.11; netifaces caveat). Badges and image names use an `OWNER` placeholder to replace with the GitHub namespace after the repo is created. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
