Refraction Sync

Description

Update Refraction documentation to reflect recent code changes. Code is authoritative — the docs follow. ## Steps 1. Run `git diff HEAD~1 HEAD --name-only` (or `git diff --staged --name-only` if reviewing staged changes) to see what changed. 2. For each changed file, determine which Refraction doc(s) are affected: - Changes to system boundaries or external integrations → update `docs/system.md` - Changes to a container's interfaces, technology, or responsibilities → update `docs/contain
