Rename binary to agent-orchestrator, add splash screen, fix white flash

- Rename Cargo package from bterminal to agent-orchestrator so WM_CLASS
  matches desktop entry and taskbar groups correctly
- Update lib name (agent_orchestrator_lib) and telemetry service name
- Add Pandora's Box splash screen with progress steps during startup
- Prevent white window flash with inline CSS and Tauri backgroundColor
