v0.4.4

Added

• Builtin overload resolution. Builtins and user-defined functions
  can now be overloaded across multiple forms; operators participate as
  named builtins in the same resolution pass.
• Scale/key quantization with user-defined scales. New scale/key
  pattern support plus a documented reference (pattern/scale-key).
• Parameter type annotations. Type names are PascalCase — Signal,
  Number, Pattern, Record, Array, String, Function,
  Stream — parsed contextually, so they remain usable as identifiers.
• Windows / MSVC build support. Source-level readiness for the Cedar
  engine and the Akkado/nkido CLI tools (ctrl-c handling, binary stdio,
  UTF-8 init, app manifests).
• Session state save/restore round-trip. A state-init codec on the
  web side serializes and restores live DSP state across reloads.
• EBNF grammar references for the core language, mini-notation, and
  chord symbols (docs/grammar/).
• Top-level MIT LICENSE.

Changed

• Audio arena memory is reclaimed during GC. Long live-coding
  sessions no longer grow the audio arena without bound; untouched
  buffers are reclaimed on sweep.

Fixed

• Hot-swapped patterns join in phase. Pattern alternation position
  is now derived from the global clock, so a hot-swap keeps the new
  pattern aligned instead of restarting its cycle.
