chore: cap every CI job with timeout-minutes (closes #294)

No workflow set timeout-minutes, so a hung build or browser held the
shared runner until the server's own limit, hours later. check now stops
at 10 minutes, e2e-firefox at 15 and e2e-chrome at 20: each is over two
and a half times the job's slowest cold-cache run. README "In CI" records
the measured times and the caps.
