feat(opencode): add oh-my-openagent plugin with omo config for ollama-cloud/glm-5.1

Configure oh-my-openagent (omo) plugin for multi-agent orchestration
using ollama-cloud and local llama-swap providers. Primary model is
ollama-cloud/glm-5.1 with fallback chains. Add runtime fallback,
background task concurrency limits, and disable incompatible agents
(hephaestus, multimodal-looker).
