g14's Go builder sat idle at capacity 2 while delivery builds waited: a puller with no room waited on its wake alone, which only a pause, a resume or a step's end gives, and it read its capacity from the settings file only when woken. The puller now follows the module's config value capacity through the runtime's watch of what mesh-config resolved (stdio.WatchConfig), uses the value it hands, and wakes on each change: no timer, no file watch, and no wait for the node-engine to fill the file again. It says when it parks and when it wakes, with its capacity.
