Loading the emulator profiles is the most expensive step of every command here, and all forty call sites used the pure-Python scanner while libyaml sat unused in the same wheel. One shared yaml_load picks the C loader when pyyaml ships it: the 375 profiles parse in 0.18s instead of 1.39s, and verify --platform retroarch drops from 2.17s to 0.73s. The loader class is the same restricted one safe_load uses. es_bios.xml was parsed straight from the network while install.py already refused a document declaring entities; both now share one guard. Scrapers reach it through a single path bootstrap in the package rather than two ad-hoc ones.
