[FEATURE] Session search in the agent view (FleetView)

Feature request

Add session search to the agent view (FleetView).

Problem

When running multiple agents/sessions, the agent view lists them, but there is no way to search across them. Once the list grows, finding a specific session means scrolling and eyeballing titles. Session search exists in other surfaces (e.g. the resume picker), but not here, which is exactly where you are when juggling many parallel sessions.

Proposed solution

A search/filter box in the FleetView agent view that matches on session title/content, the same way session search works elsewhere in Claude Code.
