panel.command.migrate module

CLI subcommand rewriting classic Panel source code to the panel.ui namespace (plan §10.1).

The heavy lifting lives in panel.command._migrate, which is only imported inside Migrate.invoke(): libcst is an optional dependency (pip install panel[migrate]), and importing it eagerly here would make it a hard dependency of every panel command, including ones that have nothing to do with migration.
