v0.4.2

• FilesystemCorpus now creates its temp file with O_EXCL (fopen(…, 'x'))
  instead of a plain write. The temp path is derived from the property id and
  pid, so on a shared corpus directory it is predictable; a pre-planted symlink
  would otherwise be followed and let a corpus write overwrite an arbitrary
  file. The exclusive create refuses the existing path, turning that into a
  skipped write (the corpus is best-effort memory, not a ledger).
• Gen::regex() / stringMatching() now reject an explicit {n}/{n,m} bound
  above 10,000 with a named error, instead of building a fixed-size array that
  exhausts memory during generation. Unbounded */+/{n,} were already
  capped by maxRepeat; only the explicit bounds were unguarded.
• Docs: documented that seed replay may run more attempts than the configured
  runs (it extends up to the recorded failing attempt so it can reproduce the
  regression), and that ValueCodec::decodeEnum() triggers the autoloader on a
  class name from the corpus document.
• Docs: SKILL.md now covers EdgeCases::None — the attribute parameter list
  and the boundary-bias rule (per-property opt-out for bodies that discard
  edge values, with the PHPUnit edgeCases() parity and the seed-alignment
  guarantee under None).
