fix: address 5 failing tests in DX bundle - async kwargs, context manager shutdown, text truncation, lazy imports
- Fix make_async() kwargs handling by wrapping with functools.partial - Fix AsyncContext hanging on shutdown by using call_soon_threadsafe - Fix truncate_text() trailing whitespace with .rstrip() - Add missing get_copilot_function and trigger_settings_update to lazy imports - Improve test to avoid unawaited coroutine warnings All 41 tests now pass (3 skipped for optional deps, 1 expected warning) 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Mervin Praison <MervinPraison@users.noreply.github.com>
