SirStone 394b3deeed SETTLED: Pattern alone is the best single gun IN GENERAL, not just vs DrussGT
Closes the one-adversary caveat that blocked shipping `onlyPattern`. Two arms
(`full` vs `onlyPattern`, rack knobs only), one frozen binary from clean HEAD
(a54ae6a, sha256 04d63cd8...), 10 adversaries, 120 battles, real server-side hit
rate, exact two-sided permutation test per adversary.

Pattern significantly WINS on 4 adversaries, ties on 3, and the full rack's three
nominal "wins" are all NON-SIGNIFICANT and only on saturated bots (83-97% hit
rate, where any gun works). **The full rack never significantly beats Pattern
alone on any adversary.** DrussGT replicates across a different frozen binary
(full 6.88 vs 6.93 prior; onlyPattern 9.99 vs 10.36/10.78 prior).

HONEST LIMITATION on the opponents: the real classic SpinBot/Corners/Crazy/RamFire
JARS are NOT runnable through the shim - `tools/robocode_shim/BotHost.java`
hardcodes `loadClass("jk.mega.DrussGT")`, and generalising it needs source edits.
So those four are the Tank Royale SAMPLE-BOT PORTS (the same opponents the shim
README validated against classic captures), not the original jars. Only DrussGT is
a real classic jar via the shim. Stated explicitly rather than implied.

Also noted: `full` in the harness passes TR_RACK_<GUN>=off for every gun, which
yields an empty admitted set and hits the documented FULL fallback ("an empty
membership admits every gun") - i.e. the shipped all-`both` rack. Verified against
the source, not assumed. Liveness proven per arm ([rack] active=..., gun_stats
100% Pattern for onlyPattern) and owner identification validated in 120/120 battles.

Follow-up if a stricter generalisation is wanted: add a generic classic-bot host to
the shim (a source change) and re-run those four as real jars.
