feat: upgrade to v3.3.1 with enhanced error handling

Major changes:
- Bump version from 3.3.0 to 3.3.1
- Update GasFeeStrategy API with min/max data size parameters
- Enhance trade return values with Optional<anyhow::Error> in buy/sell/sell_percent methods
- Fix PumpFun Mayhem mode fee recipient constant bug
- Standardize gas fee strategy parameters across all examples
- Update all examples to handle new triple return value (bool, Signature, Option<Error>)
