Update to MADSci v0.8

[RyanTheRobothead]

Summary

Lifts the module from v0.6 to v0.8 for the RAPID 446 grimm rebuild.

• pyproject.toml: pin madsci-*~=0.8.0; bump requires-python to >=3.10.
• src/sciclops_rest_node.py: rename self.node_definition.{node_id,node_name} → self.node_info.* at 4 sites (3× created_by= in _init_resource_templates() for gripper / lid_slot / plate_lid templates, 1× f"{...node_name}_gripper.nest" in _create_resources()).
• Dockerfile rewritten on the v0.8 pattern:
  • Pin base to ghcr.io/ad-sdl/madsci:v0.8.0.
  • USER root before apt-get (v0.8 base image already drops to madsci for build steps; the libusb apt-install needs root).
  • uv pip install --python ${MADSCI_VENV}/bin/python -e ./sciclops_module so the editable install lands in the venv the runtime uses.
  • Bake in a dialout_fedora group at GID 18 alongside the container's built-in dialout (GID 20) so the same image works on Ubuntu (dialout=20) and Fedora (dialout=18).
  • Fix malformed CMD ["python", "-,", "sciclops_rest_node"] → ["python", "sciclops_module/src/sciclops_rest_node.py"].
• README.md: documents the host udev rule required for raw USB access to Hudson vendor 0x7513. Without it, even a privileged container running as non-root madsci hits libusb USBError: [Errno 13] because /dev/bus/usb device nodes default to root:root 0664. The rule sets GROUP="dialout" — works on both Ubuntu and Fedora thanks to the dual dialout bake-in above.
• testing/test_sciclops.ipynb: refreshed for the v0.8 driver.

Branched off the existing madsci_0.6 branch, so the diff against main includes the full v0.5 → v0.6 → v0.8 transition that lived on that branch.

Test plan

Verified end-to-end on grimm with sciclops_plankton:

• curl /status → ready: true
• Container logs show Device Connected → CONNECTED SCICLOPS → STATUS 0000 0
• ULID 01KN09Q3YKF7W143NWYCQM242M preserved via .madsci/registry.json
• Verified host udev rule grants the in-container madsci user access to /dev/bus/usb/<bus>/<dev> for the Hudson device
