Add an HTTP endpoint on the CLI port (default 7935) that triggers the same GPU transcoding self-check that runs on startup. This allows K8s operators to configure liveness probes that detect "stuck" orchestrators where transcoding has silently broken. The implementation: - Stores a self-check closure on LivepeerNode at startup (captures the GPU devices and transcoder factory) - Registers POST /self-check on the CLI web server - Returns 200 on success, 503 on failure with error details - Returns 503 with explanation if node has no hardware acceleration Usage: curl -X POST http://localhost:7935/self-check Fixes livepeer#1920 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
