Phase 29am: CorePlan Step-A implementation (lowerer/verifier)

Goal: CorePlan で“組み立てる”移行を進める前に、CorePlan の語彙が単独でも lower/verify できる状態へ近づける。

SSOT 道筋: docs/development/current/main/design/coreplan-migration-roadmap-ssot.md

P0: Implement CorePlan::If / CorePlan::Exit lowering (minimal)

• 指示書: docs/development/current/main/phases/phase-29am/P0-COREPLAN-LOWERER-IF-EXIT-INSTRUCTIONS.md
• ねらい: 既存のルーティング/観測を変えずに、CorePlan 側の “未対応エラー” を減らす（仕様不変）
• Gate: ./tools/smokes/v2/profiles/integration/joinir/phase29ae_regression_pack_vm.sh

P1: Allow Seq-of-effects in CoreLoopPlan body (flatten)

• 指示書: docs/development/current/main/phases/phase-29am/P1-CORELOOP-BODY-SEQ-FLATTEN-INSTRUCTIONS.md
• ねらい: ループ body_bb では “Effect だけ” を前提にしつつ、Seq([Effect...]) を安全に flatten して emit できるようにする
• 非目的: If/Exit を body_bb に入れる（これは Frag/ExitMap 側の語彙で表現する）
