v0.18.0 — detect ClymandSaru template-replacement skins

Recognise and manage ClymandSaru-framework skins (e.g. jasmine_q→Ironclad, zhubao_q→Defect) as character skins. These reskin an existing character via a {modId}_config.cfg template_replacements map + a runtime DLL patch, shipping no standard animations/characters/{char}/ paths — so they were previously invisible to Skin Manager. The new ClymandSaruSkinReader reads the config as the authoritative target, which also fixes the byte-frequency suggester mis-assigning non-Ironclad skins to Ironclad (every ClymandSaru DLL embeds the literal "ironclad" default template). Creature-only reskins (e.g. reven_q→byrdpip) that target no player character are left to normal auto-mount.

See CHANGELOG.md for details.
