- Rename "Agents" scope/labels to "Applications" throughout command palette
- Remove "Exchanges" scope (was disabled placeholder)
- Implement "Routes" scope: derives routes from agents' routeIds, filterable
by route ID or owning application name
- Selecting a route filters executions by routeId
- Route results show purple icon, route ID, and owning application(s)
