Phase 75 pilots BindingId-based variable lookup in the ScopeManager and
ConditionEnv components. Demonstrates "BindingId priority → name fallback"
strategy with comprehensive testing and zero production impact.
Changes:
- scope_manager.rs: Added lookup_with_binding() trait method
- condition_env.rs: Implemented resolve_var_with_binding() with 3-tier fallback
- expr_lowerer.rs: Integrated pilot lookup paths
- condition_lowering_box.rs: Updated with BindingId support
Tests: 3/3 new pilot tests PASS (priority/fallback/legacy)
Tests: lib 958/958 PASS, normalized_dev 54/54 PASS (no regressions)
Design: Feature-gated with normalized_dev, enables Phase 76 expansion.

Extend CapturedEnv to include function parameters used in loop conditions,
enabling ExprLowerer to resolve variables like `s` in `loop(p < s.length())`.
Phase 245C changes:
- function_scope_capture.rs: Add collect_names_in_loop_parts() helper
- function_scope_capture.rs: Extend analyze_captured_vars_v2() with param capture logic
- function_scope_capture.rs: Add 4 new comprehensive tests
Test fix:
- expr_lowerer/ast_support.rs: Accept all MethodCall nodes for syntax support
(validation happens during lowering in MethodCallLowerer)
Problem solved: "Variable not found: s" errors in loop conditions
Test results: 924/924 PASS (+13 from baseline 911)

Pilot implementation of unified expression lowering for Pattern2 break conditions:
New files:
- scope_manager.rs (280 lines) - ScopeManager trait + Pattern2ScopeManager
- expr_lowerer.rs (455 lines) - ExprLowerer with Condition context support
Features:
- Unified variable lookup across ConditionEnv/LoopBodyLocalEnv/CapturedEnv/CarrierInfo
- Pre-validation of condition AST before lowering
- Fail-safe design with fallback to legacy path
- 8 new unit tests (all pass)
Integration:
- Pattern2 break condition uses ExprLowerer for pre-validation
- Existing proven lowering path preserved
- Zero impact on existing functionality (890/897 tests pass)
