v0.2.0

Added

• Bare PEP 695 type aliases now translate transparently. type Kind = Literal["a", "b", "c"] is accepted as a Model field annotation; the
  classifier unwraps the alias before dispatching. (#2)
• Union of primitive scalars is a translatable field type. int | str,
  float | str, int | float | str, and the same unions inside
  dict[str, V] and T | None are accepted. The synthesised
  panproto sort name is "Union <a> <b> ..." in canonical order; the
  encoder JSON-encodes the value, and the decoder dispatches on the
  resulting Python type. (#2, #3)
• JSON-shaped recursive type aliases translate to a single opaque
  panproto sort named after the alias. The motivating shape is the
  canonical JsonValue alias (str | int | float | bool | None | list[X] | tuple[X, ...] | dict[str, X] with X self-referential).
  The encoded form is json.dumps(value); the decoder parses and
  recursively coerces lists to tuples to satisfy didactic's
  tuple-based FieldValue type. Recursive aliases that are not
  JSON-shaped (e.g. one admitting bytes) raise
  TypeNotSupportedError with a clear message rather than failing
  silently. (#2)
