Update Documentation

Synchronize documentation with the current codebase state: one file, a category, or everything in docs/.

Anti-Hallucination Guidelines

Every statement written must trace back to a file read or grepped this run:

1. Verify each claim before writing it, read the actual source, don't recall it
2. Get counts from find/grep, never estimate ("5 services" means 5 files were counted this run)
3. Delete claims about features that no longer exist rather than leaving them stale
4. After writing, re-read the diff and drop anything not backed by evidence gathered this run
