docs: correct the counts three docs had drifted past

Each of these was true when written and stopped being true when a source
landed. dates.ts holds ten formats, not nine; INGESTION says Game8 uses
"at least four page templates" directly above a list of seven; its testing
note still credits "both current adapters" when there are eleven; PRD
lists the seven launch games against ten in GameId. AGENTS also missed
fandom from the parsers-are-keyed-by-site bullet and build-static.ts from
the tree, which matters because another section leans on the latter.

The PRD table stays as launch scope rather than becoming a roster to keep
in sync — GameId is named as the live answer instead, which is the same
move that keeps this drift from recurring. Its no-schema-change claim is
sharpened to name GachaEvent, because Reverse: 1999 did add a field:
resetHourLocal, to game metadata, which moves no stored key. The claim as
written read as false against a commit that plainly added one.

Also draws sanitize into the stage diagram as 2.5. It runs on every source
without the pipeline arranging it, which is exactly why it kept being
absent from the picture.
