- Add SiegeBot to engine/bot_strategies.go with spawn denial logic
- Implement standalone siege bot in bots/siege/ with main.go, strategy.go, Dockerfile
- Register siege bot in acb-local for arena testing
- Add test-siege-arena.sh script for validation
Strategy: Surround enemy cores to block spawning phase. Bot assigns
units to lockout rings (8 neighbors) around cores, greedily by distance.
Unassigned units collect energy or rush fully-sieged cores.
Tested: 3/10 wins vs rusher+gatherer, 1/10 wins vs rusher+gatherer+guardian
The acb-local tool was panicking when a match ended in a draw
(Winner = -1) because it tried to use -1 as an array index into
botNames[]. Fixed by checking if Winner >= 0 before accessing
the array, and printing "Result: Draw" for draws.

Add Go implementations of 5 strategy bots directly into the engine:
- GathererBot: prioritizes energy collection, avoids combat
- RusherBot: aggressively rushes enemy cores
- GuardianBot: defends cores with cautious expansion
- SwarmBot: formation-based coordinated movement
- HunterBot: targets isolated enemy units
Update acb-local with bot selection flags:
- -bot0/-bot1: select bot strategies
- -list-bots: list available strategies
- Default to gatherer vs rusher for interesting gameplay
Enables demo replays with real strategic behavior without K8s infrastructure.
