DevelopTool device tasks

The current task context supplies an absolute command prefix ending in bridge_client.py --runtime <private manifest>. Run it on the PC; the ssh subcommand executes its argument on the bound Jetson. Use that exact prefix, including its Python executable. Never read or print the private manifest or application configuration: the helper already handles authentication.

Direct routes

1. Run status; run connect if disconnected. Both use the target already configured in Remote Dev. connect verifies authentication before switching the application's active runner. No configured host: ask the user to configure Remote Dev. An expired/changed runtime: use the new context; do not retry the old target. Auto-execute must be enabled for connect and arbitrary SSH commands.
2. Execute ssh --command 'hostname; cat /etc/nv_tegra_release' --timeout 30 for device facts. Existing SSH authentication, port and sudo setup are reused. Quote the remote command as one argument; never put passwords in commands.
3. For networking, use network to open the existing sharing panel. The user selects interfaces and provides host sudo credentials there. Opening it is not sharing success. Verify gateway, public IP, DNS and HTTPS over SSH after configuration. Preserve the existing wired SSH address and original network profile. The matched jetson-pc-wired-share skill describes Linux NM behavior.
4. For cameras, enumerate /dev/video* and reuse the installed capture stack. camera start --source /dev/video0 opens the native preview. Sources also support RTSP URLs, numeric indexes and an already verified GStreamer pipeline ending in appsink. camera stop stops the preview. Device python3/cv2 is required; report a missing dependency instead of repeatedly guessing sources. Do not take a camera away from a robot controller; reuse its existing stream.
5. monitor start starts measured CPU, memory, disk, temperature and device readings. monitor stop stops polling. This does not move hardware.
6. Publish observations with publish --source arm --json '{"joint_1_deg":12.5}'. Replace the illustrative value with a real measurement. Use scalar values and units in field names. Publish after fresh observations; timestamps in the panel identify sample age. Never claim a one-time sample is live polling.
