chameleon 4.4.15

Fixed

• The auto-pass router (get_autopass_verdict) counted VCS/tooling dotfiles
  (.gitignore, .dockerignore, .editorconfig, .npmrc, ...) and ambient
  TypeScript declaration files (*.d.ts, e.g. a regenerated next-env.d.ts)
  as "files outside profiled archetypes", elevating a routine PR to needs-human
  for the wrong reason. _is_non_source_file classified them as authored source
  because its extension check never matches an extensionless dotfile
  (.gitignore.rfind(".") == 0) or the .ts tail of a .d.ts. It now excludes
  ambient .d.ts declarations and a curated set of non-source dotfiles from both
  the unarchetyped_files and source_files_changed facts, the same
  false-positive class the v4.4.12-v4.4.14 version-bump/manifest/docs work
  addressed. Real source is unaffected. See _NON_SOURCE_DOTFILES and
  _is_non_source_file in autopass.py.
