docs: finalize 0.2.0 changelog and correct 0.1.4 date

CBOR is the headline 0.2.0 feature, not 0.1.4: at v0.1.4 serial.nim was
still JSON/string-based, so the prior CBOR attribution was wrong. Also
complete the 0.2.0 scope (events, registry, codegen) ahead of tagging.

Date 0.1.4 by its last functional change (#14, 2026-05-13) rather than
the later changelog/version-bump commits, so the version reflects when
its code actually settled.

 ### Added
-- **CBOR serialization** as the FFI wire format ([#23](https://github.com/waku-org/nim-ffi/pull/23)).
+- **CBOR serialization** as the FFI wire format, replacing the previous
+  JSON/string-based `serial.nim`
+  ([#23](https://github.com/logos-messaging/nim-ffi/pull/23)).
+- **CBOR-backed FFI events**: event payloads are now serialized with CBOR
+  ([#39](https://github.com/logos-messaging/nim-ffi/pull/39)).
+- **Multi-listener event registry** (`FFIEventRegistry`) and its wiring into
+  `FFIContext`
+  ([#45](https://github.com/logos-messaging/nim-ffi/pull/45),
+  [#49](https://github.com/logos-messaging/nim-ffi/pull/49)).
+- **Event-listener ABI** with per-event typed listeners
+  ([#50](https://github.com/logos-messaging/nim-ffi/pull/50)).
+- **C++ typed per-event listeners** in the generated bindings
+  ([#51](https://github.com/logos-messaging/nim-ffi/pull/51)).
+- **Rust per-event typed listeners** (`add_on_<x>_listener` + wildcard
+  `add_event_listener`)
+  ([#52](https://github.com/logos-messaging/nim-ffi/pull/52)) and Rust event
+  example bindings/clients
+  ([#53](https://github.com/logos-messaging/nim-ffi/pull/53)).
 - **C++ binding generator** with end-to-end tests driven by CMake/CTest
-  ([#27](https://github.com/waku-org/nim-ffi/pull/27)).
+  ([#27](https://github.com/logos-messaging/nim-ffi/pull/27)), later expanded
+  with multi-context, cross-library, pipeline, and stress tests
+  ([#42](https://github.com/logos-messaging/nim-ffi/pull/42)).
 - **CDDL schema generator** for the FFI types
-  ([#24](https://github.com/waku-org/nim-ffi/pull/24)).
-- **CI pipeline**: first GitHub Actions workflow
-  parallel test
-  execution ([#26](https://github.com/waku-org/nim-ffi/pull/26)), and
+  ([#24](https://github.com/logos-messaging/nim-ffi/pull/24)).
+- **CI pipeline**: parallel test execution
+  ([#26](https://github.com/logos-messaging/nim-ffi/pull/26)),
   AddressSanitizer / UndefinedBehaviorSanitizer / ThreadSanitizer jobs
-  ([#34](https://github.com/waku-org/nim-ffi/pull/34)).
+  ([#34](https://github.com/logos-messaging/nim-ffi/pull/34)), and a
+  cross-platform OS matrix for the C++ e2e suite
+  ([#38](https://github.com/logos-messaging/nim-ffi/pull/38)).
+- CBOR type-coverage tests
+  ([#41](https://github.com/logos-messaging/nim-ffi/pull/41)).
 
 ### Changed
 - Removed the redundant `ffiType` macro; the `ffi` macro is now the single
   authoring entry point
-  ([#22](https://github.com/waku-org/nim-ffi/pull/22)).
+  ([#22](https://github.com/logos-messaging/nim-ffi/pull/22)).
+- Generated C++ avoids move constructors and assignment operators
+  ([#36](https://github.com/logos-messaging/nim-ffi/pull/36)) and no longer
+  throws exceptions across the binding boundary
+  ([#46](https://github.com/logos-messaging/nim-ffi/pull/46)).
+- Removed the wildcard event listener; event dispatch is now strictly
+  per-event ([#70](https://github.com/logos-messaging/nim-ffi/pull/70)).
 
-## [0.1.4] - 2026-06-02
+### Fixed
+- Use-after-free in the event/context lifetime path
+  ([#47](https://github.com/logos-messaging/nim-ffi/pull/47)).
