Completes b73af35. That commit stopped the cap from killing a live build, but the OTHER branch still
rebooted past the stated deadline regardless of a running build — and an agent blocked on a shell cannot
re-emit a fresh marker to extend its estimate. So a cargo-mutants run that simply overran its guess would
still be killed at the guess, throwing the work away. The deadline is an ESTIMATE; a running build is a
FACT. Order is now: absolute cap (waiting_until_max) > live build > stated deadline. The cap is the one
bound that reboots even mid-build — which is exactly how a genuinely hung build gets caught, so a runaway
still cannot park forever. Tests: live-build-defers-past-deadline, past-deadline-no-build-reboots,
cap-is-absolute-and-reboots-a-hung-build. 68 pass.
