GitPulse CLI now supports AI provider switching

GitPulse CLI version 0.2.0 is now available, bringing explicit support for switching between AI providers. Developers can set the AI_PROTOCOL environment variable to choose between OpenAI and Anthropic backends — no more reconfiguring or guessing which provider the tool expects. The release also includes a breaking change: when AI_PROTOCOL is set to anthropic, the ANTHROPIC_API_KEY is required. The OPENAI_API_KEY will no longer work as a substitute for Anthropic requests.
