Phase 29aj: PlannerOutcome observability SSOT

Goal: planner の facts/plan を 1 本の outcome に集約し、観測の SSOT を planner 側に固定する（仕様不変）。

P0: PlannerOutcome（Facts+Plan）SSOT

指示書: docs/development/current/main/phases/phase-29aj/P0-PLANNER-OUTCOME-SSOT-INSTRUCTIONS.md
ねらい: single_planner の観測が planner outcome の facts だけに依存する状態へ統一
完了: build_plan_with_facts を追加し、single_planner のタグ出力は outcome.facts 参照に収束
検証: cargo build --release / ./tools/smokes/v2/run.sh --profile quick / ./tools/smokes/v2/profiles/integration/joinir/phase29ae_regression_pack_vm.sh

指示書: docs/development/current/main/phases/phase-29aj/P2-CHOSEN_RULE-REMOVE-PATTERN1-PLANNER-FIRST-INSTRUCTIONS.md
ねらい: outcome の未使用フィールド撤去と Pattern1 の planner-first 化（仕様不変）
完了: chosen_rule を削除し、Pattern1 facts→planner を single_planner に接続

指示書: docs/development/current/main/phases/phase-29aj/P6-JOINIR-REGRESSION-SSOT-ISOLATE-PHASE143-INSTRUCTIONS.md
ねらい: JoinIR 回帰の gate を phase29ae_regression_pack_vm.sh に固定し、phase143_* は対象外を明記
対象外理由: LoopBuilder 撤去 / plugin disable 固定 / LLVM exe 期待が古い
完了: phase143_* を legacy pack に隔離し、SSOT の受け入れは JoinIR pack のみに統一
