SwiftMediaMetadata 2.0.0

Added

• Deterministic parser property tests now exercise TIFF/Exif, ISOBMFF, XMP,
  C2PA/JUMBF, and video bitstreams with truncations, malformed lengths, seeded
  byte soup, and write-read-write stability checks. A reusable script supports
  longer reproducible local runs.
• Release tooling now provides a single macOS preflight, a tag-driven GitHub
  release workflow, SHA-256 checksums, archive-content validation, and a
  step-by-step 2.0 release/Homebrew checklist.
• ImageMetadata.WriteOptions.FileModificationDatePolicy controls filesystem
  modification dates independently of timestamps embedded in media metadata.
  Use .preserveExisting for in-place edits or .set(Date) when a new output
  should inherit a source file's date. Image, video, audio, XMP sidecar, and
  batch writes share the policy.
• Mutating CLI commands accept -P / --preserve-file-modification-date.

Changed

• Breaking: the Swift package, library product, importable module, source
  target, and test targets are renamed from SwiftExif to
  SwiftMediaMetadata. Clients must use the renamed GitHub repository, depend
  on the SwiftMediaMetadata product, and replace import SwiftExif with
  import SwiftMediaMetadata. The installed swift-exif CLI command is
  unchanged.
• Image, video, audio, and XMP sidecar writes now use one internal filesystem
  transaction for atomic replacement, backups, temporary-file cleanup, and
  file attributes.
• The 33,536-city offline geolocation database is now a versioned bundled
  resource instead of 54,000 lines of generated Swift literals. Reverse
  geocoding behavior is unchanged, while a measured clean library build is 79%
  faster and the geolocation debug object shrinks from 12.0 MB to 102 KB.
