sl-perception e6065e1531 feat(jetson): camera health watchdog node (issue #198) ...

Adds camera_health_node.py + _camera_state.py to saltybot_bringup:

• _camera_state.py  — pure-Python CameraState dataclass (no ROS2):
                       on_frame(), age_s, fps(window_s), status(),
                       should_reset() + mark_reset() with 30s cooldown

• camera_health_node.py — subscribes 6 image topics (D435i color/depth
                           + 4× IMX219 CSI front/right/rear/left);
                           1 Hz tick: WARNING at >2s silence, ERROR at
                           >10s + v4l2 stream-off/on reset for CSI cams;
                           publishes /saltybot/camera_health JSON with
                           per-camera status, age_s, fps, total_frames

• test/test_camera_health.py — 15 unit tests (15/15 pass, no ROS2 needed)
• setup.py — adds camera_health_monitor console_scripts entry point
