…ults to True (python-cmd2#1682)

If this parameter is True, then completion is performed in a background thread separate from the main REPL thread. If False, completion is performed in the main thread and can block the main thread if slow.

* feat(annotated): support frozenset[T] collections

frozenset[T] joins list/set/tuple as a supported collection annotation:
it registers the same single-arg collection resolver, coerces the parsed
values into a frozenset, and rejects nested collections like the others.
Adds a do_tags example and parametrizes the container runtime-cast test
(which now also covers frozenset).

* docs(annotated): list frozenset in collection messages and changelog

Address review feedback on python-cmd2#1691: frozenset[T] was functionally
supported but the error messages and docstrings enumerating the
supported collection types still only mentioned list/set/tuple.
Update those strings so exceptions and docs accurately list
frozenset, and add a CHANGELOG entry for the new collection type.

* fix(annotated): drop unnecessary string annotations, add changelog

Address review feedback on PR python-cmd2#1692:
- Remove forward-reference quotes from _WithAnnotatedDecorator.__call__
  since Callable, _CommandParams, and _CommandReturn are already in scope
- Add a Bug Fixes changelog entry for the with_annotated type-hint fix
