Add LuxAlgo ICT/SMC Strategy Template search path

[sybapp]

What to build

Add a Strategy Template search path for LuxAlgo ICT/SMC long strategies. The template should generate Strategy Specs that enter from bullish Structure Event plus Liquidity Zone confirmation and exit on reverse bearish Structure Events, then evaluate them through session-based Walk-Forward Validation.

Acceptance criteria

• The template can vary event types, zone types, zone preference, confirmation mode, max bars after structure event, cooldown bars after exit, stop loss ticks, and max bars in trade.
• Generated Strategy Specs use type: "signal" selectors and remain schema-valid.
• Walk-Forward Validation uses RTH session-count windows, not calendar-only splits.
• Candidate ranking reports total trade count and rejects or flags candidates below the 30-trade comparison threshold.
• Tests cover template generation, schema validation, and at least one mocked walk-forward selection using signal features.
