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.

deepseek-v4-pro has been routable since v0.12 but was missing from
the _OFFICIAL_DOCS_PRICING table. Sessions using this model showed
as "unknown cost" in hermes insights instead of a dollar estimate.
Add pricing entry using published list prices:
- input: \$1.74/M tokens
- output: \$3.48/M tokens
- cache_read: \$0.0145/M tokens
Uses standard list rates (not the 75% promo) so estimates remain
accurate after promo expires 2026-05-31.
Closes#24218
