docs(release): bump to v4.4 with AOSP conformance changelog

Cherry-pick three upstream fixes: Parcel position reset in hasException()
so the method doesn't consume reply data (7804743), list_past_alias
enumeration filter inversion (2aac65c), and KeyMetadata alignment with
AOSP semantics — modificationTimeMs, Tag.ORIGIN, KeyDescriptor
normalization (86db5bf).

Additionally, createErrorReply() was missing the empty remote stack
trace header int between the exception message and error code, per
AOSP Status.cpp:196. Binder readers expecting the standard
EX_SERVICE_SPECIFIC wire format would misparse our error replies.

+## TEESimulator v4.4: AOSP Conformance
+
+- **Binder error reply format** — Aligned EX_SERVICE_SPECIFIC wire layout with AOSP Status.cpp, including the remote stack trace header field.
+- **Key enumeration** — Corrected list_past_alias pagination order to match AOSP database.rs semantics.
+- **KeyMetadata fields** — Generated key responses now include modificationTimeMs, Tag.ORIGIN, and normalized KeyDescriptor fields per AOSP Keystore2.
+- **Parcel handling** — hasException() preserves reply position for downstream consumers.

 ## TEESimulator v4.3: Performance & Reliability
 
 - **Debug log gating** — `SystemLogger.debug()` now skipped entirely in release builds, eliminating unnecessary logcat syscalls on every intercepted transaction.
