AI/Infra: Create realistic human-like AI personalities (Maia Chess)

[chinweobtagaz]

Description

Standard scaled-down Stockfish plays perfectly, then makes random obvious blunders to lower its ELO. This isn't how humans play. We need realistic Maia-like neural networks.

What Needs to be Done

• Download and integrate the Maia Chess weights (predicting human moves at specific ELO tiers: 1100, 1500, 1900).
• Configure the backend to spin up workers running these specific weights.
• Create distinct 'Bot Personalities' in the UI mapped to these models.

Acceptance Criteria

• Users can play against 'Maia 1100', 'Maia 1500', etc.
• The bot makes human-like positional errors rather than tactical completely random blunders.
• High user satisfaction reported for bot match realism.
