- Add timeout parameter to send_to_plugins_and_wait and send_to_plugin_and_wait
- Use 5 second timeout for standard operations (themes, actions, configs, etc.)
- Use 5 minute timeout for user-interactive operations:
- Authentication actions (OAuth login flows)
- Authentication requests (token refresh, OAuth)
- Template function calls (credential prompts, OAuth, etc.)
- Fixes issue where auth flows would timeout after 5 seconds
