Migrate to nixica 0.2.0 and standard CI template
Migrate from raw flake-parts + custom CI pipeline to nixica 0.2.0 with standard gitlab-ci remote include.
Changes
- Replace flake-parts + develop/ flake with nixica 0.2.0
- Expose NixOS module via flake.nixosModules
- Switch to standard gitlab-ci remote include (0.20.0)
- Add LICENSE, ChangeLog.md, .gitignore
- Remove develop/ directory and stale flake.lock
Fixes pipeline that has been failing for 12 days (invalid generated CI YAML from flake-to-gitlab-ci).
