Stacked on Scope client-provided MCP servers to ACP sessions (#140). Adds configured model selection through ACP session options using Penguin's request-scoped runtime factory, without changing global defaults or another session. Build/Plan modes propagate through trusted execution context; Plan is offered only while permission enforcement is enabled. Mode/model choices persist on resume. Read-only /status and /mcp commands are advertised and handled locally.

Provider credentials remain in existing Penguin configuration; this does not advertise interactive ACP authentication, arbitrary endpoint setup, or reasoning controls without a supported runtime path. Model selection failures preserve the current configuration.

Validation: 77 tests passed across aggregate ACP, existing model runtime, and model facade suites. Tests verify per-session model overrides, persisted selection, unknown model rejection, real write denial in Plan mode, and actual subprocess configuration wire calls. Scoped Ruff and diff checks pass. No real-editor/provider smoke is claimed.
