chore(release): bump all versions to 1.4.4

Ship the #117 cross-type attribute lookup work under v1.4.4 by bumping
every workspace version string and regenerating Cargo.lock.

Also fix a stale type_bridge.__version__ that was missed by the 1.4.2
and 1.4.3 bump commits — it still read "1.4.1" before this change.

Files touched:

- pyproject.toml: version + type-bridge-core>= pin
- type-bridge-core/pyproject.toml
- type-bridge-core/crates/{core,orm,orm-derive,python,server}/Cargo.toml:
  self version and intra-workspace dependency pins
- type-bridge-core/Cargo.lock: regenerated via cargo update -w
- type_bridge/__init__.py: __version__ 1.4.1 -> 1.4.4 (carried over)
- CHANGELOG.md: new 1.4.4 section summarizing #117

 ## [Unreleased]
 
+## [1.4.4] - 2026-04-09
+
+### New Features
+
+#### Cross-type attribute lookup (PR #117)
+
+`Entity.has` / `Relation.has` / `<Concrete>.has` — find all instances that own a
+given attribute, optionally filtered by value or expression.
+
+##### Python ORM — `type_bridge.crud.has_lookup`
+- **Cross-type form** — `Entity.has(db, Name)` returns mixed concrete subtypes across all entities owning `Name`.
+- **Concrete-class narrowing** — `HLPerson.has(db, Name)` narrows to that type and its TypeDB subtypes via `isa` polymorphism. Abstract base subclasses get subtype matching for free.
+- **Role-player hydration** — relation results always include hydrated role players. Entity lookups remain single-query; relations are re-fetched per result through `concrete_class.manager(connection).get(_iid=iid)`.
+- **`Attribute.get_owners()`** — static discovery of attribute owners without a database connection, backed by a reverse `_attribute_owners` index in `ModelRegistry`.
