Hojun-Cho 46d303f7e1 test: split fast/full, parallelize 995, race-correct two-phase test/run
test/run fans out test/wcc/*.c except 950 and 990-997 across $(nproc)
xargs workers, then runs the byte-id gates sequentially in phase 2.
Each worker writes <prefix>.status into a mktemp results dir; the
collector emits them in glob order for deterministic output. Phase 2
sequentiality sidesteps the race introduced by ww_ww writing
intermediates next to every traversed source (#15) — concurrent reads
of selfhost/cmd/<tool>/main.{combined.ww,s,o} would see partial bytes
(#16).

`make test-unit` (UNIT=1) skips phase 2 entirely for a 3.8s inner-loop
check; `make test` runs the full 132 in ~8:30. test-unit goal aligns
with the selfhost-bootstrap project goal: 990-997 + 950 are the
toolchain-rebuild gates, fast feedback is for unit work below them.

990-995 wrap every ww/w6c/w6a/w6l/wwdump invocation in `timeout 180`;
995's hardcoded /tmp/ww_d_hello.ww is now pid-keyed. 995 forks its 5
ww_ww builds concurrently (waitpid for collection) so its solo wall
drops from 3:15 to 1:32. Phase-2 split (parallel readers + sequential
writers) deferred to #17, post #15.

Wall: 9:59 → 8:32 (full) / 3.8s (test-unit, ~158× from baseline).
