Installation via SSH does not work. Installation with DID in Git URL
does not work.

Create a Typer-based CLI in src/cli.py providing the initial subcommands:
capture, ingest, query, and maintain. Wire the `distill` entry point script
in pyproject.toml so the command is available after `uv tool install`.
Remove the auto-generated main.py entry point and add a Usage section to the
README with installation and help instructions.
