Reads Pokémon ROM Hacks/Hacks/*.md as source of truth and rewrites the
static mirror tables + header counts in Index.md, Platforms/*.md, and
Bases/*.md. Dataview blocks, prose intros, and footers are preserved;
the notes themselves are never edited (curated type/rating/version safe).
Covers all 285 hacks; creates Platforms/{3DS,PC,Patch,Unknown}.md.
Supersedes the archived build-romhack-vault.py (a hardcoded 75-hack
bootstrap that would regress the live vault).
