feat: Add non-interactive installation mode for Claude Code

Makes Code Conductor installation seamless from Claude Code and other
automated environments by adding a --auto flag that bypasses all
interactive prompts.

Key improvements:
- Added --auto flag for non-interactive installation
- Smart defaults: upgrades existing installs, copies examples, commits changes
- Additional flags for fine control: --upgrade, --reinstall, --skip-examples
- Updated docs with Claude Code-specific instructions

This addresses the user experience issue where Claude Code struggled
with interactive prompts during installation.
