docs: describe other projects by facts only

Profile notes and wiki pages called .info entries phantom or incorrect, and labelled an upstream list a known defect. They now state what each file declares and what the code reads. The wiki claimed Batocera prefix-matches truncated md5s; its script compares the full string (batocera-systems:1088), which the page now says. The gaps column reads "Not read by profiles" and notes that a profile may be incomplete.
