Add Claude Code container management scripts

Scripts to run Claude Code inside an Arch Linux Docker container
that mirrors the local development environment while limiting
access to sensitive host files.

Includes per-project container isolation, a shared persistent home
directory, and a shell alias for launching Claude interactively
from any project directory.
