opencrabs 0.3.56

//! Tests for `normalize_model_for_grouping` — pin the parent-bucket
//! every quantization variant collapses into for the /usage dashboard.
//!
//! Regression anchor: 2026-05-17 screenshot showed
//! `qwen3.6-35b-a3b-ud-iq4_xs.gguf` rendering as its own top-level row
//! ($6.52, 15.5M) instead of folding under `qwen3.6-35b-a3b` alongside
//! `-gguf`, `-oq2`, `-oq4`. Root cause: the model name ended in `.gguf`
//! (file extension with a dot), and the quant patterns only matched
//! `-gguf` / `-ud-iq4_xs` / etc. so nothing stripped.
