robocode_shim: generalize bridge to any legacy bot; validate 28 champions as sparring partners

Generalize the classic-Robocode shim so the hosted bot's main class, jar, extra
classpath and data directory are configurable (SHIM_BOT_CLASS / SHIM_BOT_JAR /
SHIM_EXTRA_CP / SHIM_DATA), with DrussGT kept as the default so every existing
script, fixture and generated bot dir behaves identically.

- LegacyBotBridge: generalized bridge (DrussGTBridge kept as an alias).
- BotHost: (mainClass, jar, extraJars, dataDir); disableShield -> generic
  disableStaticBoolean.
- ClassicPeer: implement ITeamRobotPeer; synthesize StatusEvent each turn;
  make move/turnBody/turnGun/turnRadar the immediate (turn-ending) variants;
  guard re-entrant execute() from event handlers; record delivered events.
- make_botdir.sh / run_bridge_battle.sh / run_smoke.sh generalized, legacy
  invocations unchanged; generated launcher uses a per-process mktemp data dir
  so concurrent bots/battles cannot clobber one classic data directory.

Validated 35 legacy bots against a real Tank Royale battle (2 rounds vs sample
SpinBot): 28 usable (27 effective + DrussGT), 5 weak-but-playing, 2 failing.
Adds robots.json (manifest) and LEGACY_BOTS.md (how-to, status, missing-API
costs). No third-party jar is committed.
