Each og card's cold-render budget is 300 ms on the machine it was set on, scaled by how much slower the plain card renders on this one #51

The budget from #2490 was wall-clock: 300 ms on any machine. On main's check runner (half a CPU, 512 MiB) every design is ~6x slower, the plain repo card included (295 ms against 45 ms where the budget was set), and app and pull went red at 616 and 708 ms (run 889) with no change to the cards.

The test now times the plain repo card first, in the same process, and scales the budget by max(1, plain / 45 ms). A machine as fast as the one the budget was set on, or faster, is held to the full 300 ms; a slow one gets a proportionally longer budget; and a design that grows slow against the plain card still goes red anywhere. Each test prints its measured budget.

Checked: on one third of a core, main's test goes red (pull 416 ms) and this one passes (budget x2.03, pull 335 ms); with 400 ms of extra work planted in the pull card, this one is still red on a fast machine (457 ms against 300).
