"""The decomposed command modules stay lazy after `import hermes_cli.main`.

The main.py decomposition re-exports the sessions/update/dashboard command
surface from hermes_cli.main so argparse wiring and monkeypatches keep
resolving. Those re-exports must not import the modules eagerly: every
`hermes` invocation (including `hermes --version`) would pay for update_cmd's
dependency chain (jwt, click, ...) even when no subcommand runs.
