Function poll_dynamic_tool_refresh 

pub fn poll_dynamic_tool_refresh(
    service: Res<'_, ToolServiceRes>,
    agents: Query<'_, '_, Entity, With<DynamicTools>>,
    commands: Commands<'_, '_>,
)

Poll each dynamic_tools agent for a pending tool re-scan and, when the tool service reports one, tag it ToolsNeedRefresh so refresh_advertised_tools re-advertises before its next turn. Only agents carrying DynamicTools are queried, so static agents (the default) cost nothing.
