Unreleased

1.3.3 - 2026-11-01

Changed

• The code, the container image and the releases now live on Gitea (git.lucasrguerra.dev.br). The deployment pulls the image from its registry.
• The Dockerfile is multi-stage: it builds Vite from source inside the image instead of unpacking a dist.tar.gz committed to the repository (removed, along with the build:release script).
• New CI on Gitea runners (.gitea/workflows): types, 282 tests, Trivy on the repository and on the image, and an image smoke test. The image is built once per content hash and reused by the release, so a merge or a tag on an already validated commit rebuilds nothing.
• Repository links in package.json, CITATION.cff, the READMEs and CONTRIBUTING.md point to Gitea. .gitattributes forces LF line endings.

Fixed

• docker-compose.yml healthcheck uses CMD-SHELL and the correct local URL, and the port mapping honours PORT.
