feat: Add comprehensive dynamic configuration system v3.3.0

## Major Features Added ### 🎯 Dynamic Configuration System - **Environment-aware model selection**: DEFAULT_MODEL with 'pro'/'flash' shortcuts - **Configurable thinking modes**: DEFAULT_THINKING_MODE_THINKDEEP for extended reasoning - **All tool schemas now dynamic**: Show actual current defaults instead of hardcoded values - **Enhanced setup workflow**: Copy from .env.example with smart customization ### 🔧 Model & Thinking Configuration - **Smart model resolution**: Support both shortcuts ('pro', 'flash') and full model names - **Thinking mode optimization**: Only apply thinking budget to models that support it - **Flash model compatibility**: Works without thinking config, still beneficial via system prompts - **Dynamic schema descriptions**: Tool parameters show current environment values ### 🚀 Enhanced Developer Experience - **Fail-fast Docker setup**: GEMINI_API_KEY required upfront in docker-compose - **Comprehensive startup logging**: Shows current model and thinking mode defaults - **Enhanced get_version tool**: Reports all dynamic configuration values - **Better .env documentation**: Clear token consumption details and model options ### 🧪 Comprehensive Testing - **Live model validation**: New simulator test validates Pro vs Flash thinking behavior - **Dynamic configuration tests**: Verify environment variable overrides work correctly - **Complete test coverage**: All 139 unit tests pass, including new model config tests ### 📋 Configuration Files Updated - **docker-compose.yml**: Fail-fast API key validation, thinking mode support - **setup-docker.sh**: Copy from .env.example instead of manual creation - **.env.example**: Detailed documentation with token consumption per thinking mode - **.gitignore**: Added test-setup/ for cleanup ### 🛠 Technical Improvements - **Removed setup.py**: Fully Docker-based deployment (no longer needed) - **REDIS_URL smart defaults**: Auto-configured for Docker, still configurable for dev - **All tools updated**: Consistent dynamic model parameter descriptions - **Enhanced error handling**: Better model resolution and validation ## Breaking Changes - Removed setup.py (Docker-only deployment) - Model parameter descriptions now show actual defaults (dynamic) ## Migration Guide - Update .env files using new .env.example format - Use 'pro'/'flash' shortcuts or full model names - Set DEFAULT_THINKING_MODE_THINKDEEP for custom thinking depth 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

+**Default Model (Environment Variable):**
+- **`DEFAULT_MODEL`**: Set your preferred default model globally

+- **`"flash"`** → Gemini 2.0 Flash (faster responses, lower cost)
+- **Full model names** → Direct model specification
