polyscope: Add version 2.6.1

[luhenry]

• Package: polyscope
• Version: 2.6.1
• Source: https://github.com/nmwsharp/polyscope-py
• Docs: https://polyscope.run

Compiles the nanobind bindings to the Polyscope C++ viewer (GLFW, EGL, imgui/implot). Upstream publishes no riscv64 wheel.

Mirrors upstream's publish.yml with its cibuildwheel_config.toml.

Differs from upstream

• CMAKE_ARGS overridden - upstream's value lacks the leading -; EGL backend enabled as intended
• Vendored dependency licences added to the wheel

Testing

• Runs test/polyscope_test.py with the openGL_mock and openGL3_egl backends, as upstream's test_linux.yml does
• Skipped on musllinux - numpy has no riscv64 musllinux wheel in the registry

License: Wheel statically links polyscope, nanobind, robin-map, GLFW, glad, glm, happly, imgui, implot, ImGuizmo, nlohmann/json, IconFontCppHeaders (MIT/BSD/Zlib) and Eigen (MPL-2.0); upstream ships no licence text for them, so the build adds it.

Built on cp312; test results pending.
