bug(real-agent): OpenCode local config uses unavailable model omlx/quen3.5

[robertDouglass]

Summary

Trusted real-agent e2e on this machine passes claude-code -> codex but fails claude-code -> opencode because the installed OpenCode CLI exits before review with a provider/model error.

Evidence

Command run:

SK_ORCH_E2E_REAL_AGENTS=1 uv run pytest tests/e2e/test_real_agents.py -q -x --tb=short

Result:

• test_real_agent_matrix[claude-code-codex] passed
• test_real_agent_matrix[claude-code-opencode] failed because WP01 became blocked

OpenCode review log:

opencode run --agent build --format json
Model not found: omlx/quen3.5.
Unexpected server error. Check server logs for details.

Notes

This looks like local OpenCode provider/model configuration, not an orchestrator state-machine failure. Commit 97be3af improves OpenCode nested error parsing so future logs surface the actual model error instead of blank feedback.
