v1.4.2: bump version (unified release)

The KEYDB-gated test that feeds real key material into libfreemkv's AACS crypto
now composes decrypt_unit + is_clean (the removed decrypt_unit_try_keys wrapper's
behaviour), unchanged semantics.

 # Changelog
 
+## [1.4.2] — 2026-07-15
+
+Version sync with the workspace; inherits libfreemkv 1.4.2. The keydb test that
+feeds real key material into the AACS crypto was adapted to the segregated
+`decrypt_unit` + `is_clean` primitives (behaviour unchanged).
+
+## [1.4.1] — 2026-07-14
+
+Version sync with the workspace; inherits libfreemkv 1.4.1.
+
+## [1.4.0] — 2026-07-13
+
+Version sync with the workspace; inherits libfreemkv 1.4.0.
+
+## [1.3.2] — 2026-07-10
+
+### Changed
+
+- Unit keys carry libfreemkv's new `UnitKey.variant_number`; every source
+  (keydb, online, VUK-derived) emits `0` — ordinary, non-forensic content —
+  via the `UnitKey::new` constructor. No behaviour change. Inherits
+  **libfreemkv 1.3.2**.
+
