test: isolate library wheel smoke test

[bdice]

Description

Install the library wheel in a clean virtual environment and call its load_library() entry point before installing the high-level wheel or test extras. This exposes missing library-wheel runtime dependencies that the full test environment can otherwise mask.

📝 Walkthrough

Summary by CodeRabbit

• Tests
  • Added an isolated wheel validation step that installs the packaged library into a temporary environment and verifies it imports and loads successfully.
  • Existing installation and test execution remain unchanged.

Walkthrough

The wheel test script updates its SPDX header and adds isolated librmm wheel installation and native-library loading validation before the existing RMM installation and pytest steps.

Changes

Wheel validation

Layer / File(s)	Summary
Isolated librmm installation and load check ci/test_wheel.sh	Updates the SPDX header, creates and activates librmm-env, installs the librmm wheel with generated constraints, verifies librmm.load_library(), and deactivates the environment before the existing tests.

Verify each finding against current code. Fix only still-valid issues, skip the
rest with a brief reason, keep changes minimal, and validate.

Inline comments:
In `@ci/test_wheel.sh`:
- Line 25: Update the Python validation command in ci/test_wheel.sh to
explicitly assert that librmm.load_library() succeeds rather than relying on its
return code; fail the command when the function returns None, while preserving
successful execution for a loaded native library.
- Line 17: Update the virtual-environment setup in ci/test_wheel.sh to use
python -m venv --clear librmm-env, preventing stale packages across reruns. In
the native-load validation command, explicitly assert that librmm.load_library()
returns a valid handle so a None result causes a nonzero exit status.
