WBS-8.7: spec-code synchronization expanded to 66.4% (93/140 files)

Coverage improvement: 24.07% (39 files) → 66.4% (93 files)
- Tagged 54 additional spec files with has_code_implementation: true
- Covered: strategy/*, risk/*, exit/*, formulas/*, governance/*, contracts
- Target: 50% (81 files) — EXCEEDED by 12 files

Files tagged:
- spec/strategy: 20 files (action_matrix, entry_core, entry_gates, etc.)
- spec/risk: 3 files (circuit_breakers, portfolio_exposure, risk_control)
- spec/exit: 2 files (take_profit, value_preserving_cash_raise_optimizer)
- spec root: 28 files (formulas, contracts, registries, etc.)
- spec/03_formulas: 2 files (formula_registry, output_field_owner_ledger)
- spec/data_quality: 1 file (expectations)
- spec/fields: 1 file (field_dictionary)
- spec/formulas: 1 file (manifest)

Impact:
- Improved LLM radar discoverability for spec-to-code linkage
- Ready for WBS-9.6 (LLM document optimization phase)
