fix: include bridge agents in total agent count

The totalAgents calculation was missing bridgeAgents.length,
causing the header to show an incorrect count when bridge agents
(like Architect) were present.

This also fixes a pre-existing issue where the component could
show 'No results' when a search matched only bridge agents.
