docs: keep inventory counts out of the GitHub repo description

The description is repo metadata, so check_counts cannot see it, and it went
stale twice (#448, then 16/27/64/76 against 18/29/66/80). It now leads with
what the pack does and carries no numbers; CLAUDE.md says to keep it that way.

Closes #486
