Align MCP/CLI naming and resolve default model/mode server-side (#291)

* Align create_agent naming and resolve defaults server-side

* Fix test assertions for default model/mode resolution

- Use config.model and config.modeId instead of non-existent snapshot.model
- Strip legacy "default" model ID in normalizeConfig
- Update runtimeInfo assertion to expect resolved default model

* Fix CI: update CLI test for --title, fix formatting in checkout-git
