"""obsidian-wiki installer CLI.

Python port of ``setup.sh`` for the pip-installed package. The skill content
lives inside the installed package (``obsidian_wiki/_data/skills``) instead of a
cloned repo, so this wires the bundled skills into every supported AI agent's
skills directory and writes ``~/.obsidian-wiki/config`` so the skills resolve
the vault from any project.
