Retromod

Stable release ("the general update"). Promoted from 1.2.0-rc.2 with no code changes since that candidate: a final full build + test pass, self-hash re-embedded. The 1.2.0 line accumulated across 1.2.0-snapshot.1–snapshot.9 → rc.1 → rc.2 (the sections below have the details); headline work over 1.1.0 includes Forge 26.2 hosts (EventBus 6→7 bridge), 26.x worldgen for structure mods (Yung's family), a 1.12.2 pre-1.13 Forge baseline, Sinytra-parity correctness fixes, and Forge→NeoForge synthetic bridges. The final rc.2 fixes: OreBlock → DropExperienceBlock (#145, Isle of Berk), the nested ExtendedScreenHandlerType$ExtendedFactory redirect (#147, VillagerViewer), and the docs-site Probe security fix (DOM-XSS + jar-reader hardening) with an accuracy pass (deep-integration mods such as Applied Energistics 2 now correctly read as incompatible; the mixin note counts actual mixin classes).
