Fix Crush workflow model forwarding for non-interactive runs

[Copilot]

Smoke Crush was failing even with an explicit workflow model because the Crush engine definition exported CRUSH_MODEL but never passed it to crush run. That left Crush to resolve its own default large/small models, which in CI fell through to unintended provider auth paths and failed during startup.

• Root cause

  • The declarative Crush engine config set model state in env only:

    model-env-var: CRUSH_MODEL

  • But the generated command did not include a model flag, so the configured workflow model was not actually selected by the CLI.

• Engine definition

  • Add model-flag: --model to the Crush engine behavior definition.
  • This makes gh-aw render the configured workflow model into the generated execution command instead of relying on Crush-side defaults.

• Generated command behavior

  • With a configured model, execution now renders the equivalent of:

    crush run --verbose --model "$CRUSH_MODEL" "$(cat /tmp/gh-aw/aw-prompts/prompt.txt)"

  • Without a configured model, no model flag is emitted, preserving existing default behavior for unconfigured workflows.

• Regression coverage

  • Extend Crush engine tests to assert:
    • the configured model is forwarded as --model "$CRUSH_MODEL"
    • the model flag is omitted when no model is configured

Addressed in deb69aa. I updated the Crush engine config to write provider base_url entries into .crush.json, forward the configured workflow model to both --model and --small-model for non-interactive runs, and recompiled smoke-crush.lock.yml.

Addressed in 2ae2c00. The Smoke Crush workflow now uses the Crush-supported copilot/claude-sonnet-4.6 model, inline Crush skills are written to .crush/skills, and smoke-crush.lock.yml was recompiled.
