Force Node.js 24 in all GitHub Actions workflows to suppress the
upcoming Node.js 20 deprecation warnings. Disable vue/html-indent and
vue/html-closing-bracket-newline ESLint rules that conflict with
Prettier formatting.
Closes#122
Replace hardcoded version strings with build-time injection:
- Frontend: Vite __APP_VERSION__ from env or package.json
- Backend: APP_VERSION env var exposed via /health endpoint
- Docker: build arg propagated through both stages
- CI: release workflow extracts version from git tag
Document branching strategy and release process in CONTRIBUTING.md.
Catch up CHANGELOG with v0.2.0 and Unreleased sections.
