minimize core dependencies

Keep core dependencies minimal in configuration files like pyproject.toml. Non-essential packages should be added as optional dependencies or placed in extras sections rather than as required core dependencies. This prevents package bloat and allows users to install only what they need.

When adding new dependencies, first determine if they are truly required for core functionality. If the dependency is only needed for specific features, testing, or optional functionality, use the appropriate configuration section:

# Core dependencies - only essential packages
[tool.poetry.dependencies]
python = "^3.9"
requests = "^2.28.0"

# Optional dependencies for specific features
[tool.poetry.extras]
rich-output = ["rich>=13.0.0"]
anthropic-support = ["anthropic^0.50.0"]

# Development/testing dependencies
[tool.poetry.group.dev.dependencies]
pytest = "^7.0.0"

This approach maintains a lean core package while providing flexibility for users who need additional functionality.
