v0.0.3 — Pokémon Emerald (pre-boot launcher)

Adds the shared recomp-ui Dear ImGui pre-boot launcher: pick your ROM/BIOS, tune display/audio/controls, rebind keys, then play. Real box art + Game Boy Advance controller art, GBA identity (SHA-1) verification, and settings that persist next to the exe. Skip with --no-launcher or the in-launcher toggle.

Built against gbarecomp + recomp-ui as pinned git submodules.
