When switching models at runtime, the config_context_length override was not being passed to the new context compressor instance. This meant the user-specified context length from config.yaml was lost after a model switch. - Store _config_context_length on AIAgent instance during __init__ - Pass _config_context_length when creating new ContextCompressor in switch_model - Add test to verify config_context_length is preserved across model switches Fixes: quando estamos alterando o modelo não está alterando o tamanho do contexto
