v0.10.0

Added

• OpaqueMerge mixin, opaque class decorator, and TypedNamespace base for
  customizing typed_merge, all exported from the package root.
  OpaqueMerge/opaque mark a type opaque (last object wins, no field
  introspection — for a fully-built config object or one with factory-function
  field hints); TypedNamespace applies _parse_<field> coercers at
  construction. The __merge__ and _parse_<field> extension hooks are now
  documented in the merging guide.

Changed

• YAML !include/!load auto-registration now logs a WARNING when it
  overrides a constructor already registered on the loader class, so a
  redundant manual yaml.add_constructor("!include", ...) is visible rather
  than silently replaced.
