feat: enhance daemon dispatching, device readiness fallback, and live streaming UI

- Admin Console & Task Queue: add cancellation, session startup progress endpoints, and support ingress metadata
- Diagnostics & Runtime: enhance ADB probe to prefer unlocked devices and synchronize with readiness engine
- MCP Server: dispatch tasks through Artemis Daemon scheduler with fallback to standalone runner, improve action overlays
- Showcase UI: improve session auto-selection with pinning support, render startup progress, and refine stream styling
- CLI & Makefile: expose server lifecycle commands (restart, stop, status)
- Configuration: ignore runtime server state file in .gitignore
