Before:
Nothing told PyMoDAQ that the PiCamera and daqhats viewers only work on a Raspberry Pi: on another system they fail at initialization with an import error.

After:
DAQ_2DViewer_PiCamera and DAQ_1DViewer_daqhats declare supported_platforms = ('linux',) and supported_architectures = ('aarch64', 'armv7l'). PyMoDAQ refuses to initialize them elsewhere, with a message. The ZMQ based viewer and actuator run on any system and stay undeclared, so the package classifiers are unchanged (check_plugin --fix-classifiers: up to date).

How: one class attribute pair per plugin class (PyMoDAQ >= 5.3.5 reads it, older versions ignore it).

Tested: files compile, package_platforms reads the declarations. Not tested: initialization on a Raspberry Pi or on another system; the choice of aarch64 and armv7l comes from the picamera2 and daqhats requirements, not from a run on the board.

The tests jobs fail while installing the dependencies: picamera2 needs python-prctl, which cannot be built without the libcap development headers ("You need to install libcap development headers"). The same Tests workflow is already red on main (run of 2026-09-29), and this PR only adds two class attributes, so the failure is not from it. A fix would be to install libcap-dev in the workflow of the plugin (rollout PR #15 is still open); I did not widen this PR for it.
