green-nx 1.0.18 — sharpness

A small, focused one: the picture gets a sharpness control.

Sharpness (Settings → Sharpness)

The streamed image is a touch soft — H.264 at cloud bitrates smears fine detail, most visibly when docked on a 1080p screen. This release adds luma-only sharpening to the video shader: Off / Low / Medium / High, off by default.

• Luma-only means chroma is untouched — no color fringing.
• An overshoot clamp keeps hard edges from growing halos.
• Effectively free on the GPU (a few extra texture taps in the shader that already runs).
• Persisted as "sharpness" in settings.json; applies from the next stream start.

Start with Low — it recovers detail without side effects. High is deliberately crunchy and can ring on UI text.
