These drive real git processes against a local bare remote, so their cost
is process spawns competing with every other Vitest worker. Measured on
CI they take 23-30s each, and the 30s override was crossed by 37ms, so the
run failed on wall-clock rather than on behaviour.
Replace the three hand-picked 30_000 values with one documented constant
at 120_000, which keeps a genuine hang visible while clearing the observed
spread. The global default stays at 10s so nothing else is loosened.
