Implement production, trade, and technology upgrade logic for game engine

[Copilot]

Implements core game mechanics for factory production queues, market trading with depreciation, and technology upgrades with character buff application.

Changes

Produce.cs

• Production queue per team with async Task-based processing
• Atomic CAS resource deduction prevents race conditions
• Production parameters: Semiconductor(10r/5s), Medicine(5r/4s), Toys(1r/2s), Clothes(8r/6s), Food(3r/1s)

Trade.cs

• Buy: Characters load goods from team factory with capacity validation
• Sell: Market prices with ×2 multiplier, 10% depreciation per 100 units sold
• Score calculation: revenue × 10 per game rules
• Depreciation applies to future sales, not current transaction

Uplevel.cs

• Tech upgrades consume power and apply buffs to all team characters
• HP tech: +50% max HP with proportional current HP increase
• Attack tech: +30% power
• Speed/Efficiency tech: +1 efficiency stat
• Carry tech: +50% capacity
• Cached enum values to avoid repeated allocations

Game.cs

• Wired Trade() and UplevelTech() APIs to partial class implementations
• Added InitProductionQueues() to constructor

Thread Safety

All implementations use ConcurrentDictionary, AtomicInt/AtomicLong, and CAS operations where appropriate.

// Atomic resource check and deduction
while (!resourcesDeducted) {
    int current = factory.Source.Get();
    if (current < needed) return;
    if (factory.Source.CompareExROri(current - needed, current) == current)
        resourcesDeducted = true;
}
