chameleon 4.4.2

Fixed

• Per-edit PostToolUse no longer repeats the "N files import X" cross-file
  importer note for an export the edit left in place. That note is
  edit-independent static context already delivered pre-edit by the "Inbound
  callers" section, so on a large module every additive edit re-listed one note
  per exported symbol, all about symbols the change never touched — the dominant
  per-edit noise source. posttool_verify now drops it on BOTH the daemon and
  in-process lint paths; the removed-export existence break, the explicit
  lint_file tool, the Stop backstop, and Bash-writes still see the full
  importer surface.
• The Ruby/Python default-export-kind mismatch no longer fires on a
  mixed-construct module that does not actually define the expected construct.
  Ruby and Python have no single default export, so the shape is a best-effort
  "primary construct" guess; the check now suppresses when the expected
  construct is absent from the file's top-level kinds. TypeScript, which has a
  genuine unique default export, is unchanged.
• unittest / Django TestCase hook methods (setUp, tearDown, setUpClass,
  setUpTestData, asyncSetUp, and the rest) are exempt from the Python
  snake_case method-naming rule. They are framework-mandated camelCase a class
  must match exactly, so flagging them was an unfixable false positive.
• A Python class Foo(object): is no longer read as a missed inheritance. It is
  identical to class Foo: in Python 3, which the check already left alone, so
  an explicit universal object base is not a deviation (the extension-point
  wrapper false positive).
• The pre-write reuse-before-create nudge no longer offers a class-bound member
  as an importable "reuse" target. A method, classmethod, staticmethod, Ruby
  def self.x, TypeScript constructor, or TypeScript get/set accessor is scoped
  to its class — "import and reuse it" only fits a free, module-level function,
  so a same-named class member on another class (expired on a queryset,
  perform on a service) was wrong advice. The softer semantic pass still
  surfaces a renamed near-duplicate, and genuine body duplication is still
  caught at turn end.
