Merge current backend main into human decisions

Why: The W4b verifier branch must include the current compiled-plugin host option surface before review.

Evidence: Focused extension, app, server, and command-bus tests pass after preserving both public API additions.

Impact: The public surface advances to 2.23.0-experimental and exposes both human-decision and compiled-plugin capabilities.
