feat(joinir): Phase 40-3.5 route switching implementation
- Add collect_assigned_vars_via_joinir() in if_phi.rs (65 lines) - Wrapper using Phase 40-1 JoinIR infrastructure - Converts ASTNode to JSON and calls JoinIR analysis - Add route switching in loop_builder.rs - Check HAKO_JOINIR_ARRAY_FILTER env flag - Route A: Legacy collect_assigned_vars path - Route B: JoinIR collect_assigned_vars_via_joinir path - Add A/B tests in phase40_array_ext_filter_test.rs - phase40_ab_route_switching: Basic assignment detection - phase40_ab_nested_if: Nested if assignment detection - All 5 Phase 40 tests PASS 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
