There was a conflict with per-target compile flags and the PCH. The PCH was causing the game code to be built without the inlining flags actually taking effect (internal `src/dusk` files did not use them), which caused mods to fail to resolve static functions for hooks. Fix: split Dusklight internals (`src/dusk/`) into a separate static library altogether, cleanly allowing us to disable inlining and patching flags only for internal code while also fixing the PCH flags issue. Additionally, this updates symgen to v1.3.4, which includes a fix for GCC function fragments and specializations getting resolved as display name aliases, conflicting with the actual functions. Aurora also updated to include https://github.com/encounter/aurora/pull/244
