v0.4.3

Fixed

• Compile no longer blocks the audio thread. Recompiling a patch
  used to stall process() for the full duration of akkado_compile
  (~110 ms median, ~158 ms peak on heavy patches like the unison-pad),
  causing audible silence on every hot-swap. Compile now runs in a
  dedicated Web Worker that owns its own WASM instance; the
  AudioWorklet only receives pre-packed bytecode + state-init buffers
  via the new loadProgram message.

Changed

• Rapid recompiles supersede-by-newest. Holding Ctrl+Enter no
  longer queues a long backlog of compiles; every new compile gets a
  monotonic generation tag and stale results are silently dropped, so
  only the latest source ever lands in the worklet.
• Compile worker recovers from crashes. If the worker is killed
  (WASM trap, OOM, browser kill), the next compile() surfaces a
  "worker crashed — restarting" diagnostic and the call after that
  respawns the worker and succeeds — no page reload required.
