mpv-ios v0.1.2

Prebuilt libmpv XCFramework and MPVKit Swift Package for iOS.

Assets:

• Libmpv.xcframework.zip — binary framework only
• MPVKit-v0.1.2.zip — full Swift Package (framework included)
• checksum.txt — SHA-256 checksum for binaryTarget(url:checksum:) in a remote Package.swift

Fixed

• buildscripts/scripts/libass.sh: the iOS device (arm64) build
  failed at the final link step with ~24 undefined _ass_*_neon symbols
  from libmpv-combined.a. libass's autotools build (Makefile.am)
  never lists its own libass/aarch64/*.S NEON asm sources — only its
  Meson build does — so the archive shipped a dispatcher that calls NEON
  functions with no object code backing them. Rebuilt libass with Meson
  • Ninja instead, matching every other Meson-based dependency in this
    repo (docs/RESEARCH.md #37).
