@senior: issue #29 — derive Ollama Cloud provider models from the agent registry

The agent→model registry in route.sh is now the single source of truth for
Ollama Cloud model IDs. route.sh publishes the full registry as a step
output (agents=...), and install-opencode.sh derives the ollama-cloud
provider models: map from it (unprefixed IDs), instead of hardcoding a
second copy. The two files can no longer drift silently — adding/changing
a cloud model in the registry automatically updates the provider config.

- route.sh: emit agents=$(jq -c '.' /tmp/agents.json) to GITHUB_OUTPUT
- agent.yml: pass steps.prep.outputs.agents as AGENTS env to install-opencode.sh
- install-opencode.sh: derive CMODELS from $AGENTS; // {} keeps it valid
  when no agent uses an ollama-cloud model (non-ollama repos)
