refactor(honcho): delegate _is_trivial_prompt wholly to the shared classifier

Simplify-pass finding: sharing only the REGEX left the wrapper logic
(empty/strip/slash checks) duplicated, half-defeating the no-drift goal.
The classmethod now calls agent/memory_provider.is_trivial_prompt directly;
_TRIVIAL_PROMPT_RE stays as a class attr for backward compatibility with
any external referents.
