dua-core v5.0.1

Bug Fixes

• fall back when macOS bulk directory reads are unavailable
  The new implementation can have a performance impact if the bulk reads are turned
  off, but this can be controlled with configuration so shouldn't be a problem.
  Also, it's for old systems.

  PowerPC and macOS before 10.10 do not provide getattrlistbulk, so
  unconditional native directory enumeration leaves dua-core consumers
  with an undefined symbol at link time.

  Select bulk reads from the target architecture and deployment version in
  build.rs. Respect MACOSX_DEPLOYMENT_TARGET, otherwise query the target
  compiler's default; unknown versions and architectures use ordinary
  directory reads. Keep the existing macOS entry/metadata API and preserve
  requested APFS clone metadata in the fallback.

  Review identified an unused 64 KiB allocation per directory in fallback
  builds. Make that buffer zero-sized, avoiding the heap allocation while
  keeping the shared reader layout and fallback behavior.

  Also omit clock_gettime before macOS 10.12, leaving the metadata probe's
  existing missing-clock behavior in place.

• avoid reading past HEADER_SIZE in Windows ReadDir::entry_at
  FILE_ID_BOTH_DIR_INFO has a 104-byte fixed header (HEADER_SIZE) followed by FileName: [u16; 1] (2 bytes) and 6 bytes of trailing alignment padding (size_of::<FILE_ID_BOTH_DIR_INFO>() == 112).
