fix: resolve Taskmaster AI MCP integration with local Ollama models

- Fix provider configuration from 'openai' to 'ollama' in .taskmaster/config.json
- Remove conflicting MCP configurations (.cursor/mcp.json, packages/.cursor/mcp.json)
- Standardize on single .vscode/mcp.json configuration for VS Code
- Update environment variables for proper Ollama integration
- Add .env.taskmaster for easy environment setup
- Verify AI functionality: task creation, expansion, and research working
- All models (qwen2.5-coder:7b, deepseek-r1:7b, llama3.1:8b) operational
- Cost: /run/current-system/sw/bin/zsh (using local Ollama server at grey-area:11434)

Resolves configuration conflicts and enables full AI-powered task management
with local models instead of external API dependencies.
