PenguinBurner v0.4.4

First tagged release of the 0.4 line (since v0.2.6). The experimental latency stack is dormant by default — a plain launch shows present-FPS with zero trace overhead; latency features require explicit opt-in.

Auto-UV & Auto-OC

• Carry the Auto-OC clock offset through to the final/saved verification row; the Undervolting runs table now shows applied/limit MHz correctly, and non-OC rows read — instead of a misleading 0/0.
• Distinct efficiency / balanced / performance VF-curve tail shapes.

In-game overlay, latency & adaptive (opt-in)

• New in-game Vulkan overlay (native present-path layer) showing present-FPS, clocks, voltage, and power.
• Opt-in PC latency telemetry (--experimental-ingame-latency) and opt-in display (present→scanout) latency folded into the LAT number. All latency features default off.
• Adaptive Auto-UV: switches between efficiency/balanced/performance profiles from achieved FPS vs an Adaptive UV Target; holds the startup tier when no FPS feed is present.

UI

• Reordered tabs to Auto-UV / Profiles / Overlay.
• Compacted the Undervolting runs table; renamed the Decision column to Result.
• Renamed the overlay Target FPS control to Adaptive UV Target.
• Default overlay update interval of 1s for new users.

Packaging & docs

• Documented gamescope for headless/server Q2RTX stability runs; a lighter Wayland-free Xvfb path is planned.
• Large README/feature-docs overhaul; repo restructured into focused packages (common/, runtime_support/, nvidia_driver/, native latency-layer split).
