feat(aot): enhance CollectionsHot with backward receiver type resolution
Implement `resolve_recv_type_backward` to infer Array/Map receiver types by backward MIR analysis, reducing Unknown types in get/set/has rewrites. **Implementation:** - New function: resolve_recv_type_backward (collections_hot.hako:152-215) - Traces MIR output backward in [lb, k) range - Analyzes newbox/copy/phi chains with depth limit (12) - Returns "arr"/"map"/"" (unknown) - Integrated into rewrite loop as priority step 3 (after type_table and peek_phi, before method disambiguation) - Diagnostic logging with NYASH_AOT_CH_TRACE=1 - "[aot/collections_hot] recv_backtrace => arr|map" **Benefits:** - Reduces Unknown type count in externcall rewrites - Improves Array/Map get/set optimization coverage - No CFG changes (jsonfrag=0, structure preserved) **Testing:** Pending resolution of unrelated Stage-3 local keyword issue 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
