Account Goal monitors total equity (PnL + starting balance).

When your equity reaches: Goal + Buffer amount, Copilink:
1. Auto-flattens all positions
2. Optionally disengages the account

Example:
- Starting Balance: $50,000
- Account Goal: $3,000
- Goal Buffer: $100
- Flatten triggers at: $53,100 equity

The buffer accounts for slippage when flattening.
