[BUG] Python wheel missing generated code (_generated/ not included)

[bburda]

Bug report

Steps to reproduce

1. Build wheel: cd clients/python && python -m build
2. Inspect contents: python -m zipfile -l dist/*.whl

Expected behavior

Wheel contains ros2_medkit_client/_generated/ with all generated API and model code.

Actual behavior

Wheel is missing _generated/ entirely. The api/*.py modules import from _generated and fail with ModuleNotFoundError at runtime.

Root cause

_generated is a symlink (_generated -> ../../generated). Hatchling does not follow symlinks outside the package directory when building the wheel.

Fix

In the publish CI job, replace ln -sf with cp -r so the generated code is physically present inside the package directory before building.

Also in build-and-test job, use cp -r for consistency - symlink works for local dev but not for wheel builds.

Environment

• ros2_medkit_clients version: main (post PR fix(ci): publish Python wheel to GitHub Releases #10 merge)
• Spec version: 0.4.0
• OS: ubuntu-latest
