[Tobias-Fischer]

Each PR in this stack (#221 → #222 → #223 → #224 → #225) is one commit and builds on the previous one; together they supersede #217.

Recipes, snapshots and build workflows now come from vinca-rs, a Rust rewrite of vinca. It reuses pixi-build-ros for package.xml parsing, the requirement rules and the build scripts, and rattler-build's crates for rendering.

Changes

• vinca-rs 0.1.7 comes as a conda package from the prefix.dev channel tobias-fischer/robostack-tools, built by its release workflow, so no CI job compiles it.
• rs <d> generate-recipes runs vinca-rs generate. Already-published recipes are matched by exact name, version and build string, which rattler-build's own renderer computes, so -n is gone from testpr.yaml.
• rs <d> gha runs vinca-rs workflow from .github/build-template.yaml. That template carries what robostack.py used to patch into vinca-gha's output: run name, concurrency, per-distro token secret, contents: read, env. The job steps live in .github/actions/build-recipes, so a job is a few lines and many more jobs fit GitHub's 500 KiB limit.
  • Each job needs only the jobs building its dependencies, not the whole previous stage. A failure then only skips what depends on it.
  • vinca-rs workflow --json writes vinca-gha --json: write the batched stages instead of a workflow vinca#201's stage format, with the same ids, so Staged builds for pull requests and releases #216 can switch to it.
• rs <d> create-snapshot runs vinca-rs snapshot: the same output as vinca-snapshot, in 23 s instead of 6 min.
• check-deps, pinning and rebuild planning read requirements from vinca-rs requirements; check-deps solves in one vinca-rs process (humble osx-arm64: 161 s → 30 s).
• The ros-<distro>-* compatibility packages are noarch: generic: every platform's jobs build and upload them, and the upload skips what's already there.
• CI: the pull request workflow and its jobs are named by what they do, and its runs are grouped by a fixed key.
• Additional recipes: vinca-rs requires an override: reason when an additional recipe replaces a released package (Raise an error if snapshot and additional_recipes are conflicting vinca#126). Those the releases caught up with are dropped: the autoware packages that lyrical and rolling took from humble "until released", humble's mujoco_vendor and rolling's rtabmap. rolling's autoware_lanelet2_extension thus builds its release 1.1.0, with its patches refreshed (rclcpp includes; the GCC-only warning flag not passed to MSVC). The remaining overrides got reasons.

What changes in the packages
vinca-rs was compared with vinca 74d1e85 (RoboStack/vinca#200) by meaning, for every distro and platform: the same recipes, sources, patches, build numbers, metadata and test files. The intended differences:

• Install check: every ament package gets a package_contents test for its package.xml (Automatically add existence tests vinca#108).
• Conda-forge wrappers: packages that only wrap a conda-forge package depend on just it and the mutex; about 20 per distro and platform are rebuilt once.
• One build script per recipe: platform selectors are resolved at generation.
• Build types: ROS 2 CMake packages get a CMake script without catkin/ROS 1 parts; a package without <build_type> that builds with ament_cmake* is ament (async_web_server_cpp, mrt_cmake_modules).
• Python variants: conditional_python_dependency (Conditionally build Python-dependent Lyrical libraries across Pythons 3.12-3.14 #193) is supported, with conditions evaluated (condition part of the dependency tag is ignored in some case vinca#189).
• humble tracetools is rebuilt: remove_host: [pkg-config] now also removes the native-only host pkg-config.

Tested

• Build-branch-style runs of the new workflow for humble with uploads off: linux-64 22/22 and win-64 19/19 built and tested.
• pixi run rs check passes, and pytest tools/tests passes.

Notes

• vinca-rs uses pixi-build-ros and rattler-build from unmerged PRs (feat(pixi-build-ros): RoboStack's rosdep mappings per distribution, one lookup shared with RoboStack prefix-dev/pixi#7533, #7539, #7540, #7541; feat: honour --skip-existing in --render-only and continue past solve failures prefix-dev/rattler-build#2943) until they land.
