Summary

Fixes #1327 - clawdbot message --channel telegram fails with Unknown channel: telegram.

Problem

The Commander code path calls ensureConfigReady() in preAction but doesn't load the plugin registry. Channel plugins like Telegram are registered during plugin loading, so getChannelPlugin('telegram') returns undefined.

Solution

Add ensurePluginRegistryLoaded() call in preAction for commands that need channel plugin access:

• message
• channels
• directory

Changes

const PLUGIN_REQUIRED_COMMANDS = new Set([
  'message',
  'channels', 
  'directory',
]);

// In preAction hook:
if (PLUGIN_REQUIRED_COMMANDS.has(commandPath[0])) {
  ensurePluginRegistryLoaded();
}

Testing

• TypeScript compiles cleanly
• Commands that don't need plugins remain fast (no plugin loading)
• Commands that need plugins get them loaded before action runs
