feat(roms): add Obsidian vault knowledge base for 75 library romhacks

build-romhack-vault.py generates pokemon-romhack-vault/: one note per hack
(YAML properties + tags + summary + links), an Index MOC (Dataview + static
table), a Types taxonomy, and per-platform MOCs. Dataset is the single source
of truth — edit + re-run to extend.
