v1.7.21 — Per-Agent Model Routing in OpenCode

Changes

Sub-agents now run on their configured model — The background-agents plugin previously passed only the agent parameter to session.prompt(), which didn't apply the target agent's model config. Sub-agents always inherited the orchestrator's model.

Now resolveAgentModel() reads the agent's model field from opencode.json and passes it as { providerID, modelID } to session.prompt(). If you configure sdd-spec with Opus and sdd-explore with Sonnet, each phase will actually use its assigned model.

Parity with agent-teams-lite 67eb832.
