-- ============================================================================
-- VENV-SELECTOR: Python virtual environment manager
-- ============================================================================
-- Provides a Telescope-based picker to select and activate Python virtual
-- environments. Supports multiple venv types: anaconda, pipenv, poetry, hatch,
-- pyenv, and standard virtualenvs. Automatically activates cached venvs.
-- Keymaps:
--   <leader>vs - Open venv selector picker
--   <leader>vc - Select cached venv
-- Autocmd:
--   Auto-retrieves cached venv when opening Python files with pyproject.toml
-- ============================================================================
