Subject: [PATCH] Add pantor/ruckig LLAR Formula (v0.17.3)

Translate the Conan Center `ruckig` recipe into an idiomatic LLAR Formula.

- versions.json: module path pantor/ruckig, no external deps (the cloud
  client is disabled, so the vendored third_party headers are not built).
- Ruckig_cmp.gox: semver comparator for the v-prefixed tags.
- v0.17.3/Ruckig_llar.gox:
  - onBuild uses the CMake helper to build the core static library,
    disabling examples, tests, the Python module and the cloud client
    (mirrors the Conan recipe) and installing the full public interface
    (headers, libruckig.a, CMake config); metadata "-lruckig".
  - onTest reproduces the Conan test_package consumer in an independent
    build tree so it works on both cache miss and cache hit.

Verified with `llar test -v ./pantor/ruckig@v0.17.3` (fresh build + test,
cache-hit test, and explicit --os linux --arch amd64).

Closes #20
