v2 no longer ships opencode on trunk. The skill now:
- Fetches origin/providers
- Copies opencode source files to their target paths
- Appends self-registration imports to both provider barrels
- Adds @opencode-ai/sdk@1.4.3 as a pinned agent-runner dep
- Adds OPENCODE_VERSION ARG + opencode-ai pnpm global install to Dockerfile
- Rebuilds host + container
All steps idempotent. Credential/env/Zen docs unchanged.
