Subject: [PATCH] fix: include hermes_plugins in gateway.log component filter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

gateway.log uses a _ComponentFilter that only passes records from
loggers starting with ('gateway',). Plugin modules are loaded under
the hermes_plugins.* namespace, so all plugin log output is silently
dropped from gateway.log.

This makes plugin registration — which directly affects gateway hooks
(pre_gateway_dispatch, transform_llm_output, etc.) — invisible in
the gateway-specific log. Operators debugging gateway behavior check
gateway.log and see no plugin activity, even when plugins are working
correctly.

Add 'hermes_plugins' to the gateway component prefixes tuple so
plugin log messages appear in gateway.log.

Closes #28138
