- Register plugin command in CLI main.py imports and add_typer calls
- Add plugin to valid_cmds list in main() to prevent "Invalid command" error
- Remove unused PluginNotFoundError import from plugin.py (F401 lint fix)
- Fix line too long in plugin.py _print_plugin function (E501 lint fix)
- Fix list_plugins to output JSON even when no plugins installed
- Remove duplicate step definitions from plugin_cli_steps.py that conflicted
with existing steps (I run, output should contain, output should be valid JSON)
- Rewrite plugin_cli.feature to test error cases that don't require pre-registered
plugins (since PluginManager is not a singleton across CLI invocations)
- Implement plugin CLI subcommand group with list, show, enable, disable, install, remove commands
- Add JSON/YAML output format support for all plugin commands
- Create Behave BDD tests for plugin CLI functionality
- Full type annotations and pyright compliance
- Supports plugin state management (ACTIVATED, DEACTIVATED, DISCOVERED, ERRORED)
