defaultTailLines used Bun.spawn(['tail',...]), but the ccs server (and
'ccs bar launch') runs under node where Bun is undefined — it threw, the
per-path catch swallowed it, and Codex quota silently never appeared in real
deployments (it only worked under the bun-run dev harness). Replace with a
pure fs read: runtime- and OS-agnostic, no subprocess. Verified under node:
surfaces a live rollout's rate_limits (primary/secondary).
