feat(config,app): embedding provider=ollama 배선 + endpoint, version 0.26.0

kebab-config: EmbeddingModelCfg.endpoint: Option<String>(serde default, ollama용,
None→models.llm.endpoint 폴백) + provider 문서에 ollama + env
KEBAB_MODELS_EMBEDDING_ENDPOINT. kebab-app embedder(): provider match 에 ollama
분기(facade 경유). workspace member += kebab-embed-ollama, app dep 추가.
