//! Omni-engine-loop: the never-explode gulp, the pure-integer quant score, and extract -> register ->
//! place.
//!
//! Port of ASOLARIA-AS-NEURAL-NETWORK@4cc7624 `tools/behcs/omni-engine-loop.mjs:17-78`. The resident
//! set is bounded at `max_resident` regardless of input volume. `extract_register_place` mints through
//! the ported `github_pid_register::mint_pid`; `omni_engine_loop_cycle` takes string rows (the
//! `typeof row === 'string'` key of :62).
