fix: make cyclonedds optional and add click dependency

Move cyclonedds to optional dependencies since the Python bindings
require the native CycloneDDS C library which is not available in
standard CI environments. All mock-based tests run without it.

- cyclonedds moved to [project.optional-dependencies] so uv/pip
  won't attempt to build it unless explicitly requested
- click added as direct dependency (was used but undeclared)
- TestIdlTypeCollisions skipped when cyclonedds unavailable
- Follows same pattern as gpiod driver (platform-conditional dep)
