spec: split meeting-room-architecture (runtime-only rewrite, step 4 / part B)

Boss-zone sections moved to .workshop/.wiki/concepts/workshop-architecture.md
(commit aa263fd in workshop repo). Full original spec preserved in git history
prior to this commit.

Also: log.md entries for the split event and this rewrite.

Untracked: .brainstorm/, .wiki/raw/naming/ — these are originals still here,
removal scheduled for step 13 (final split-done commit).
