ci: one queue for all of CI, nothing cancelled (#140)

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.

+### 19. #140: one queue for all of CI, nothing cancelled (2026-11-11)
+
+- **Found again:** Build runs 245 and 247 (the board images and the v4 tests) were cancelled at 0 s on
+  two pushes to PR 164's branch: the push queued Build in the shared `qemu` group, the PR's
+  Acceptance run joined seconds later, and a group keeps one running and **one waiting** run -- the
+  joining run cancelled the waiting one. The v4 tests were run by hand instead (79 programs, 0
+  failures; `logs/20261111-193825/v4-test`).
+- **Ruled** (Captain Bob): "It should be global" -- one queue for all of CI. The runner
+  (`starshipos-vps`) has capacity 1 (Captain Bob: "capacity is 1").
+- **Built:** the `concurrency:` block is gone from all six workflows, each with a comment saying why;
+  `.claude/CLAUDE.md`'s CI section corrected. With one runner at capacity 1, every job of every
+  workflow waits in Gitea's queue and none is cancelled; a runner-image rebuild still blocks the rest
+  (2026-11-07). What changes: the runner takes **jobs**, not runs, so another workflow's job may run
+  between two of Build's -- never beside one; one QEMU at a time holds.
+- **Left to Captain Bob:** the offline duplicate runner registration (id 1, also `starshipos-vps`) --
+  removed, it can never take a job if it comes back. #140's "Done when" is met by this entry and the
+  workflows' comments once it reaches `master`.
