Original field-string entity search with actual comparator

RE-856. Reproduce with python3 scripts/analyze_qvm_entity_field.py; focused validation: cargo xtask test-group entity-field. Machine report.

150 original 276505 searches and 256 actual 69386 comparisons recover cursor/active/null-field filtering, ASCII folding, signed high-byte ordering, embedded NUL, nullable pointer order and zero-count behavior. Source calls the comparator with99999. Safe finite strings only; raw invalid pointers and runtime integration remain open.

Original executable/native runtime and complete Linux/macOS Rust/Bevy/Solari acceptance remain unverified.
