Prvw v0.7.0

Added

• ICC color management: embedded source profiles (JPEG, PNG, TIFF, WebP) are transformed to accurate output colors.
  Level 1 converts to sRGB, Level 2 targets the actual display profile via CoreGraphics FFI
  (CGDisplayCopyColorSpace). Images without profiles assumed sRGB. Display changes flush the cache and re-decode
  (ee226ac,

• View menu toggles: "ICC color management" (Cmd+Shift+I) and "Color match display" (Cmd+Shift+C), both persisted in
  settings. Disabling ICC grays out color matching (L2 depends on L1)

Changed

• ICC engine: replaced lcms2 (C bindings) with moxcms (pure Rust, NEON SIMD). 24MP transform: 247ms -> 45ms on M3 Max.
  No C toolchain needed for cross-compilation

Fixed

• Screen detection: replaced unreliable current_monitor() + CGDisplayBounds position matching with
  NSWindow.screen.deviceDescription for authoritative CGDirectDisplayID

• Pre-existing BGRA->RGBA swap bug in screenshot capture
