Phase 29ap: Legacy extractor reduction (Step-E)

Goal: Reduce legacy extractor fallbacks while keeping planner+composer as the SSOT path.

What changed

• JoinIR legacy loop table removed; router now delegates to plan/composer only.
• stdlib loop subsets migrated to plan facts (StringUtils.to_lower, StringUtils.join, trim_start/trim_end).
• Pattern2/4/8/9 legacy routing removed; Pattern6 nested minimal adopted via CorePlan (strict+release).
• Dead-code cleanup after legacy removal (unused JoinIR lowerers removed).

Gate (SSOT)

• ./tools/smokes/v2/profiles/integration/joinir/phase29ae_regression_pack_vm.sh

Commands (SSOT)

• ./tools/smokes/v2/run.sh --profile quick
• ./tools/smokes/v2/profiles/integration/joinir/phase29ae_regression_pack_vm.sh

Residuals / Next

• Next phase is TBD (choose between Plan/Composer subset expansion or CorePlan vocabulary expansion).
