Release v0.3.0

Changelog

Breaking Changes

• Breaking Change: The model_overrides configuration now requires explicit model names for DeepSeek V4 Pro and Flash Free variants. Previous shorthand syntaxes are no longer supported.
• Breaking Change: Anthropic model routing now prioritizes Zen-specific endpoints over legacy Anthropic routing when IsZen is true. Existing Anthropic configurations may require updates to use model_overrides for compatibility.

New Features

• Add full Zen model support including Claude, GPT, Gemini, and free-tier models
• Add Claude model overrides for sonnet-4.6, opus-4.7, and haiku-4.5
• Add DeepSeek V4 Pro Zen override to config example and default config
• Add 49 Zen models grouped by endpoint type in models command output
• Add MiniMax M3 and Qwen3.7 profiles to model configuration
• Add grok-build-0.1, big-pickle, and north-mini-code-free models to config listing
• Add test coverage for Claude, Grok, Big-Pickle, North Mini-Code-Free, and missing Go models

Bug Fixes

• Fix endpoint classification to use Zen-specific routing (minimax uses chat completions on Zen)
• Fix streaming/non-streaming path checks to prioritize Zen over Anthropic routing
• Fix deprecated model names in documentation

Improvements

• Improve model documentation with updated endpoint tables and configuration examples
• Enhance configuration examples with DeepSeek V4 Pro/Flash Free override patterns
