v1.3.2

PATCH - security hardening follow-up: closes the dir-symlink residual the wx-latch left open. mkdirSync(recursive) silently follows a symlink pre-planted at the marker subdir (bypassing the 0o700 mode) - an lstatSync no-follow check now rejects a symlink subdir and fail-closes. Completes the CodeQL js/insecure-temporary-file mitigation. One-flock across CoalMine/CoalHearth/CoalFace. Tests green; verify PASS.
