The full local unit run was about 16 minutes on my PC because every Robolectric class gets its own JVM and they ran one after another. Locally it now uses one test JVM per four cores, at most four (six ran my 32 GB PC out of memory). CI still runs one JVM since that's where the 30 s waits got missed before, and -Ptest.forks=N still overrides both.

Also picks up the TodayWeekPagerTest fix from fix/week-pager-flake (wait for the day cross-fade before checking for Missed), which never made it to main.

Measured with :core:domain:test :core:data:testDebugUnitTest :app:testFossDebugUnitTest :app:testPlayDebugUnitTest --rerun, 803 tests, 16 threads / 32 GB:

	Runs	Failures	Flakes	Total time per run
Before (1 JVM)	3	0	0	964 s, 966 s, 965 s
After (4 JVMs)	3	0	0	337 s, 337 s, 335 s

No failures or flakes in any of the six runs (two earlier baseline runs were green too), so no test code changed besides the cherry-pick. I tried -XX:TieredStopAtLevel=1 for the test JVMs, no difference. Single tests get a bit slower under parallel load, the run as a whole gets about 3x faster.

Slowest 20 tests (mean of 3 runs and both flavours):
