Working on multi-agentic architecture. I'll be on vacation next week.

The main branch is stable and cherrypicked up to 0.4.1. Meanwhile, I'm working on refactoring to multi-agentic architecture. Like the last release, which dramatically refactored how context is handled, this change is touching virtually every part of the project. While I hope to have it done AND merged before I leave on Friday -- it is a huge job. So one of two things will happen:

1. I'll finish, merge and release 0.4.1 including subagents
2. I'll release 0.4.1 (basically 0.3.4 + cherrypicks + bugfixes) and merge the subagentic branch into 0.5.x when I get back.

So either 0.4.1 agentic happens this week or 0.5.x agentic happens in 2 weeks (or we skip to 6).
