- Integrated LoopBodyLocalInitLowerer into Pattern2 lowering - Fixed ValueId double-allocation issue (delegate to InitLowerer) - Added body_ast parameter to lower_loop_with_break_minimal() - Fixed json_program_loop.rs test for body-local scope - New test: phase191_body_local_atoi.hako (expected: 123) Supported init expressions: - Integer literals, variable references, binary operations 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
