v0.4.0

Nightfall v0.4.0 — UI Overhaul

New Features

• Screen curvature — Flat / Slight Curve / Curved modes with proper UV mapping
• Screen tilt — Pitch on grab (no roll), 3° sticky snap, adjustable sensitivity
• Black bezel border — Curves and resizes with screen, toggleable
• Starfield environment — 3-state passthrough: On → Off → Starfield
• Welcome screen — Connect/Options buttons on screen mesh, click-forwarding via UV
• Right-click via grip — Correct Limelight button code with debounce
• Scroll via thumbstick — OpenXR vector2, adjustable sensitivity
• Quest Touch Plus controller models — Runtime FBX loading with textures
• Corner resize handles — Proper curved placement, thicker collision

Fixes

• Right-click now uses Limelight button code 3 (was sending middle-click)
• UV mapping uses asin() for curved screens
• Corner handles track _mesh_size (not screen_mesh.mesh.size which is zero on ArrayMesh)
• B button toggles UI via OpenXR is_button_pressed("by_button")
• Connect button shows "Connecting..." and disables during pairing
• UI panel starts hidden, menu grab bar lowered
• Starfield stops during streaming, resumes on disconnect
