## Flee Threshold Changes
- Reduced flee threshold from AttackRadius2+4 to AttackRadius2 (no buffer)
- Modified bots: farmer, gatherer, siege
- Bots now only consider enemies in actual attack range, not preemptively
- Added outnumber logic: only flee when nearbyAllies < nearbyEnemies
## Behavior Vector Changes
- Derive aggression from actual kill rate (not self-reported)
- Formula: behaviorVec[0] = min(killRate, 1.0)
- Preserves existing economy value or defaults to 0.5
- Enhanced logging to show derived aggression value
## Rationale
Aggression must be economically necessary, not just rewarded.
Previous flee logic created a false safe option that discouraged combat.
Now bots only flee when actually outnumbered within combat range.

All 10 non-gatherer bots included timestamp in the request verification
signing string but the engine (auth.go SignRequest) does not include
timestamp. Every incoming turn request failed 401 verification, bots
crashed after 10 turns, and all matches ended in stalemate.
The engine documentation in auth.go is also misleading (old comment
mentioned timestamp in signing string) but the actual implementation
never included it. Fixed all language implementations to match.
Affected: random (py), swarm (ts), hunter (java), guardian (php),
rusher (rs), assassin (rs), phalanx (rs), opportunist (go),
farmer (go), scout (py), raider (java)

Economy-maximizing bot that prioritizes energy collection and spawning
while avoiding combat entirely. Seeks nearest uncontested energy via BFS,
flees enemies within 3 cells, avoids contested energy tiles, and stays
near active cores for maximum spawn throughput. Includes 12 unit tests.
