Hojun-Cho 9b99d0883f make: content-keyed test-commit tier caches the 10 pure gates (test-perf T1) ...

The 990-997/950/989_lib_byteid gates are pure functions of (stage
binaries, tracked sources, fixtures, harness, Makefile) and eat 87% of
full-test wall (measured, .ai/testperf-baseline.md). test-commit hashes
exactly those inputs; a match with the last green full run reports the
gates as 'cached' (counted separately, never silently) and runs
everything else - 25s vs 212s on a hit, full run on any miss. A red
run never records the key; make test itself is never cached and stays
the pre-push bar (rule 14 updated). Key gap caught in review:
examples/ feeds 996_dyn_ww - included.
