Merge master into StarForth-v4.0.0: the six runner.capacity comments

Captain Bob, 2026-11-13: "I merge master in". PR 164 could not merge:
master's six comment-only commits of 2026-11-11 (751bfe26..268e5593,
"record runner.capacity: 1 decision ... (FABRIC-3, #140)") edit the
concurrency blocks the branch deletes for #140 ("It should be global").

Resolved in every workflow for the branch -- no concurrency group --
with master's fact kept as a line of the #140 comment: the capacity is
explicit in the runner's config.yaml, runner.capacity: 1. Each file
parses; scripts/test_acceptance_signing.sh passes.
