feat: spin off Pokémon ROM-hack catalog from homelabstack

Curated knowledge base + pipeline for the valhalla Pokémon ROM-hack
collection, moved out of the homelabstack infra repo on 2026-06-06 so that
repo stays focused on the homelab.

- pokemon-romhack-vault/      Obsidian vault: 75 hack notes + Index/Types/Platform MOCs (generated by build-romhack-vault.py)
- scripts/                    build-romhack-vault, romhack-import/fetch/apply
- pokemon-romhacks-wanted.md  manual-acquisition list (gated hacks)
- drop/                       gitignored ~1.3GB binary staging area

The ROMs live on valhalla (/storage1/Emulation) served by the RomM stack,
which stays in homelabstack (stacks/roms).
