DOCS v0.1.13 github

@hatch:hud v0.1.6

Immediate-mode HUD overlay for the WrenLift game framework. HUD.new(g) gives you hud.label, hud.rect, hud.button — drawn through @hatch:gpu's Renderer2D, with click + hover state tracked across frames. Ships a built-in 5×7 procedural font (digits + uppercase + common punctuation) so HUD essentials (SCORE: 100, LIVES: 3, PAUSE) work without bringing an asset font. Adds HUDPanel — an immediate-mode debug control panel that stacks slider / toggle / button / text / divider rows top-down inside a fixed-width box so procedural-world demos can expose every knob (wind strength, water amplitude, sun angle, terrain seed) at runtime without rebuilding the bundle.
