docs(changelog): drop premature 0.2.0; fold into Unreleased at 0.1.4

The branch carried a dated `[0.2.0] - 2026-06-04` release section and
`version = "0.2.0"` while the active release line is still 0.1.x, which
misrepresents unshipped work as a released version. Treat 0.1.4 as the latest
release and move everything above it back under `[Unreleased]`, merging the
0.2.0 bullets into the existing Added/Changed/Fixed groups. Set the package
version to 0.1.4 and realign the example `requires` (>= 0.2.0 -> >= 0.1.4) so
they stay satisfiable.

 ## [Unreleased]
 
-### Changed
-- Enforce `-d:noSignalHandler` at compile time: the build now fails with an
-  actionable message unless the consumer sets `-d:noSignalHandler` (libraries
-  embedded in a foreign host such as Go/Rust) or `-d:ffiAllowSignalHandler`
-  (standalone Nim binaries). Prevents the Nim runtime from installing its own
-  OS signal handlers and clobbering the host's — the cause of a real status-go
-  regression.
-- User event callbacks now run on a dedicated event thread fed by a
-  bounded SPSC queue (default capacity 1024), so a slow listener can no
-  longer block the FFI thread or concurrent `add_event_listener` /
-  `remove_event_listener` calls
-  ([#6](https://github.com/logos-messaging/nim-ffi/issues/6)).
-- Replaced the dedicated watchdog thread with a heartbeat check that
-  runs on the event thread. The FFI thread advances an atomic heartbeat
-  each loop iteration; if it stalls for more than 1s past the start-up
-  grace window, the event thread emits the `not_responding` event.
-
 ### Added
 - Queue-overflow handling: when the bounded event queue is full, the
   library sets a sticky "stuck" flag, logs an error, fires
   `not_responding` from the event thread, and rejects subsequent
   `sendRequestToFFIThread` calls with `event queue stuck - library
   cannot accept new requests`.

-## [0.2.0] - 2026-06-04
-
-Major release introducing the CBOR-based wire format, CBOR-backed FFI events
-with a multi-listener registry, multi-language binding generation (C++, Rust,
-CDDL), CI hardening with sanitizers, and several robustness fixes around
-context lifetime and memory safety.
-
-### Added
 - **CBOR serialization** as the FFI wire format, replacing the previous
   JSON/string-based `serial.nim`
