v0.17.0

Added

• Per-adapter model pinning: agents.<name>.model now pins a model on grok, opencode, pi, kimi, cursor, and antigravity, in addition to claude and codex. A registry places each adapter's model flag where that CLI expects it, so model = "grok-composer-2.5-fast" on a grok agent runs Grok Composer under a Brigade run. brigade roster doctor validates every pin and fails before dispatch when an adapter can't pin a model or when an ollama: ref carries a stray model =. Ollama cloud models run through the existing ollama:<model> ref, e.g. ollama:qwen3-coder-next:cloud.

Fixed

• The grok, amp, and crush writer adapters invoked a --prompt flag that none of those CLIs accept, so every run through them failed at argument parsing. They now use each CLI's real one-shot form: grok -p, amp -x, and crush run.
• brigade roster doctor no longer crashes on endpoint-mode agents (endpoint + model, no cli); it reports the endpoint and skips the CLI model-pin check.
