Use the same exact-score known-crop preference as best_lens in the built-in fixed-lens fallback. Preserve higher-score priority and cover both profile orders through the public lookup API.
Validated with 33 lensdb and 5 engine lens-profile tests, plus full cargo xtask ci (8/8, Rust 1.95.0, Apple M5 Max Metal and WASM). The new tie regression fails against the previously published selector. No workflows or lockfile changes.
