ai/worker: Add scope pipeline support to worker and build scripts (#3814)

* Add scope pipeline support to worker and build scripts

This commit adds support for the scope pipeline in the go-livepeer worker:

Worker Integration:
- Updated ai/worker/docker.go to map scope modelID to
  livepeer/ai-runner:live-app-scope image in livePipelineToImage map
- Added test case in ai/worker/docker_test.go to verify scope image
  mapping works correctly

Build Scripts:
- Updated box/build-runner.sh to accept scope as a valid pipeline
  option alongside streamdiffusion and comfyui

These changes enable the orchestrator to recognize and schedule scope
pipeline containers for live-video-to-video requests.

* Update CHANGELOG
