nyash-codex 0ff96612cf docs(joinir): Phase 63 - AST ownership analyzer (dev-only)
ASTNode → OwnershipPlan の解析器を追加(analysis-only, normalized_dev)。

Key changes:
- New ast_analyzer.rs (~370 lines):
  - AstOwnershipAnalyzer: AST → Vec<OwnershipPlan>
  - ScopeKind: Function/Loop/If/Block
  - Invariants: owned_vars/relay_writes/captures/condition_captures

Design:
- JSON v0 "Local=rebind" を使わず、AST の Statement::Local を正しく扱う
- "読むのは自由、管理は直下だけ" アーキテクチャ維持

Tests: 3 unit tests + 47/47 normalized_dev PASS
- loop_local_carrier_is_owned_and_written
- condition_capture_is_reported_for_loop
- relay_write_detected_for_outer_owned_var

Next: Phase 64 - P3(if-sum) 本番ルートへ dev-only で接続
