fix(joinir): Phase 196 Select double-remap bug in instruction_rewriter
Root cause: PHI inputs were being remapped twice in instruction_rewriter.rs
- Line 304: remap_instruction() already remapped JoinIR → Host ValueIds
- Line 328: remap_value() attempted to remap again → undefined ValueIds
Fix: Only remap block IDs, use already-remapped ValueIds as-is
Test results:
- phase195_sum_count.hako → 93 ✅ (multi-carrier P3)
- loop_if_phi.hako → sum=9 ✅ (single-carrier P3)
- loop_min_while.hako → 0,1,2 ✅ (Pattern 1)
- joinir_min_loop.hako → RC:0 ✅ (Pattern 2)
- No [joinir/freeze], no regressions
