Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to Disabling hot reload now preserves watch channels and prevents listener errors and log flooding. The change is localized and unit-tested, but lifecycle documentation still contradicts the new disabled-mode behavior and should be updated with owner awareness.

Update the start documentation for the new lifecycle.
The documentation at Lines 38-39 still says that no task is spawned when hotreload is disabled. This code now spawns the task intentionally so that the watch senders remain alive. Describe the disabled-mode task behavior instead.

In the context of #1536 I tried to disable hot-reloading configuration and that is currently causing the main `Reloader` object to be dropped and closing all its `watch::Sender`s, which in turn causes all receiver ends to constantly return errors that are ignored by all components listening on them and flooding the logs with messages of configuration being reloaded. This is fixed by keeping the reloader task alive when hot-reloading is disabled, but having it ignore any attempts to reload the configuration.

Of note, this has been broken since the original implementation, it is only noticeable now because there are some components that become noisy when the channels are dropped.
