Defame1297 a8beff7d2c perf(kyberforge): parallelize the bats and shell test runners ...

Both runners spawned one process at a time and let it finish before starting
the next, so wall time scaled with file count even though each file's own
work (bats: mostly repeated apm/git subprocess startup; the vale-heavy
shell scripts: repeated vale binary startup) rarely used a full core.

run-bats.sh now backgrounds one `bats` invocation per file, bounded by core
count, buffering each file's TAP output so concurrent streams can't
interleave, then flushes in stable sorted order once every job finishes.
run-tests.sh does the same for test-*.sh in fixed-size batches (plain `wait`,
not `wait -n`, to stay on the bash-3.2-safe path test-vale-wrap.sh already
enforces for this file) -- verified beforehand that every test-*.sh keeps its
fixtures under its own mktemp dir rather than mutating the live repo tree, so
running them concurrently is safe.

Confirmed correct on both the pass and fail paths (a deliberately failing
bats test and a scratch TEST_DIR with pass/fail/skip-77 scripts) before
measuring: full bats suite 26-30s -> 7.5s, tests/run-tests.sh 68s -> ~45-50s,
full pre-push gate 2m40s -> 1m12s.
