Teknium 6036793f60 fix: clearer docker backend preflight errors (#1276)
* feat: improve context compaction handoff summaries

Adapt PR #916 onto current main by replacing the old context summary marker
with a clearer handoff wrapper, updating the summarization prompt for
resume-oriented summaries, and preserving the current call_llm-based
compression path.

* fix: clearer error when docker backend is unavailable

* fix: preserve docker discovery in backend preflight

Follow up on salvaged PR #940 by reusing find_docker() during the new
availability check so non-PATH Docker Desktop installs still work. Add
a regression test covering the resolved executable path.
