refactor: split vite_package_manager into vite_workspace and vite_install (#261)

# Rename vite_package_manager to vite_install and extract workspace functionality to vite_workspace

This PR splits the functionality of the former `vite_package_manager` crate into two more focused crates:

1. `vite_install` - Handles package manager detection, installation, and commands (install, add, remove, update)
2. `vite_workspace` - Manages workspace detection, package discovery, and dependency graph building

The separation provides clearer responsibilities and better code organization:
- `vite_install` focuses on package manager operations
- `vite_workspace` handles workspace structure and relationships

Added README files to both crates to document their primary responsibilities.
