test: parallelize test/run via xargs -P; 180s per-tool timeout

Browse Source 
test/run fans test/wcc/*.c across $(nproc) workers via xargs -0 -n2 -P
$JOBS; each worker writes <prefix>.status and an optional <prefix>.fail
sentinel into a mktemp results dir. The driver collects in glob order so
output stays deterministic across runs.

Wraps every ww/w6c/w6a/w6l/wwdump invocation in 990-995 with
`timeout 180`, bounding orphan compilers under 8-way contention. The
direct runwait(exe) calls for fresh-built test binaries get the same
treatment via a "timeout 180 %s" snprintf hop. Motivation: pid 2101 was
a w6c_ww that ran 42h on /tmp/wcas_asm_1326_15.ww until we killed it
during this session; timeout makes that impossible.

993's /tmp/ww_d_hello.ww is now pid-keyed (snprintf %d getpid); without
it concurrent runs (or future shards of 993 itself) would race on the
staging file.

Wall: 9m59s → 4m31s on 8 cores. Same 132/132 status.
