Test module for StrategyBuilder

Test Categories:
1. Initialization - name, base_instrument, base_freq
2. add_indicator() - Fluent API, returns IndicatorSpecWrapper
3. set_base_blueprint() - Required before build
4. add_advanced_blueprint() - Multiple blueprints
5. build() - Returns StrategyConfig
6. Dynamic factory - Indicator type lookup
