v0.1.6

• Adds explicit W8A8 checkpoint support documentation for the Quark INT8 route, including the tested nameistoken/Qwen3.6-27B-Quark-W8A8-INT8 checkpoint.
• Updates the launcher display to separate the real vLLM --quantization value from the display-only W/A type (W4A16, W8A16, W8A8).
• Adds launcher service-status cache reporting for running services. Live used values and 30-second refresh are shown only when vLLM exposes real cache-usage metrics; otherwise the launcher reports total cache capacity only.
• Improves launcher startup preflight for large single-file checkpoints and cleans up residual vLLM processes after failed launches.
• Fixes launcher stop handling so orphaned vLLM API servers, worker processes, and resource trackers are discovered and cleaned up instead of leaving VRAM occupied.
