Complete Pass 3 on Wild Gunman (U) and Joypad Test Cartridge (U)

- Wild Gunman (U): Updated OVERVIEW.md to Pass 2/3, added SpriteOamTable comment at , fixed build path references
- Joypad Test Cartridge (U): Updated OVERVIEW.md to Pass 2/3, fixed build path references
- Donkey Kong Jr. (JU): Fixed root OVERVIEW.md summary table (was Pass 1, actually Pass 2/3 per project OVERVIEW.md)
- Root OVERVIEW.md: Updated summary table (Wild Gunman & Joypad Test Cartridge → Pass 2/3), updated observation notes

All projects verified byte-identical.

-- **Promotion** — move to a top-level `Joypad Test Cartridge (U)/` folder, add `header.s` / `chr.s` + full-ROM `make` target (as e.g. `Burger Time (U)`), then join the root `OVERVIEW.md` numbered inventory.
-- **Pass 3 continuation** — name data tables (button mappings at $C000–$FFFF, test patterns), refine zero-page aliases for the untraced code region.
+- **Promotion complete** — moved to top-level `Joypad Test Cartridge (U)/` folder with full ROM build (`header.s`, `chr.s`, `linker.cfg`, `Makefile`).
+- **Optional deeper Pass 3 work** — extract button mapping and test pattern tables from untraced regions into labeled `.byte` blocks; refine remaining zero-page aliases.
