Every workflow shared the concurrency group qemu. A group keeps one running
and one waiting run, and a run that joins cancels the one waiting: Build
runs 245 and 247 were cancelled at 0 s by PR 164's Acceptance runs.
Captain Bob, 2026-11-11: "It should be global"; the runner has capacity 1.
So the concurrency block is removed from all six workflows (a comment in
each says why): with one runner at capacity 1 every job waits its turn in
Gitea's queue and none is cancelled, and a runner-image rebuild still
blocks the rest. CLAUDE.md's CI section corrected; FABRIC-3 XLVIII.19.
