v1.5.1

• Fewer false-positive IPs in Windows PE files — compiler-emitted u16 tables (unwind
  info, C++ exception metadata, jump tables) no longer get mistaken for sockaddr_in
  structures.
• ~5x faster tests — cargo test drops from ~95s to ~17s via opt-level = 2 on the test
  profile.
• Rust 2024 cleanup and dependency updates.
