The six suites that spawn coordinated worker subprocesses or bind local
endpoints (index_supervisor, daemon_application, daemon_runtime,
daemon_frontend, daemon_bootstrap, daemon_ipc) ran in the parallel wave,
where the saturated 3-4-core CI runners starve their fixed readiness
deadlines: index_supervisor waits at most 3 s for a worker marker while
the worker is a full re-exec of the ASan runner plus the admission
handshake. Both macOS legs failed the same four readiness assertions
deterministically and ubuntu-latest added four daemon_frontend and one
daemon_runtime timing failures, while an idle machine passes the same
suites 6/6 in the wave.
Moving them to the quiet serial tail follows the runner's existing rule
for this class (cli/subprocess/watcher/...) and also keeps the shared
per-account coordination namespace free of cross-suite admission
traffic. Same suites, same tests, same union-guarded totals - only the
schedule changes. Locally re-verified: 6742 passed, 0 failed, 2 skipped
(120 suites, 17 serial-tail).
