Summary

The producer reports camera faults and offers the management channel. A camera that cannot start (no power cable, no GMSL link) no longer ends the producer: a supervisor reports the fault in plain words, retries, and resumes streaming once it is fixed.

• An optional WebSocket management channel (off unless --control-token-file names a shared secret) reports status and the fault and retargets a stream's direct link to a new PC address at run time. SIPL pipeline notifications are named so the fault table can tell a lost link from a failing sensor, and the driver's own log lines are captured with a start failure.
• The producer binary links sensing::control and installs under a producer install component, which the deploy script packages.

Depends on two PRs. The management channel and the producer's supervisor are #1465, which is based on the LiveKit producer; this branch is based on the producer PR (#1468), which sends video over the direct link instead. A PR has one base, so the branch carries #1465's library and the same producer wiring ported to this producer's capture backends. What this PR adds to that is the direct link: set_direct_target retargets a stream's direct link to a new PC address at run time, and each stream's status reports its direct host, port, connection and error. After #1465 merges, this branch is rebased and the repeated library and wiring commits are dropped, which will need conflict resolution in main.cpp and the plugin README.

Validation

• Compiled and linked on a Jetson Orin (SIPL build) with the Jetson Multimedia API and SIPL headers: camera_plugin_sensing built and a release was packaged, not started. The library's sensing_control_tests (90 cases) pass on a PC; pre-commit and clang-format-14 are clean.
• Not run: the management channel and the fault path have never run on hardware; no camera has been unplugged against it. Only one camera has been streamed to the PC, and no latency claim is made.

Closing as superseded: the camera path is now the camera_streamer architecture (SIPL/Argus sender, AVS1 over TCP, PC receiver and LiveKit bridge; see #1473-#1479). Not merged; the branch and commits are kept.
