migrate-mmwlisted

<purpose> Migrate mark-my-words data files from the old flat `~/.things/` layout to the per-plugin `~/.things/mark-my-words/` directory structure. This moves voice profiles and renames the blog working directory. This skill handles **data file relocation only**. Config migration (config.yml -> config.json + preferences.json) is handled by `/things:setup-things`. Run `/things:setup-things` first if config.json doesn't exist yet. </purpose> <steps> <step id="check-prerequisites" number="1"> <description>Check Prerequisites</description> <load-config> <action>Resolve the user's home directory.</action> <command language="bash" output="home" tool="Bash">echo $HOME</command> <constraint>Never pass `~` to the Read tool.</constraint> <read path="<home>/.things/config.json" output="config" /> <if condition="config-missing">Tell the user: "Run `/things:setup-things` first to initialize your .things directory."
