tokenUsage summed the usage line of every review document in HEAD: the
report had no window, and every week repeated the whole history.
A document now enters a week's tokens when the commit that added it to
dev falls in [since, until]. fetchSnapshot reads the committer date from
git log -M --diff-filter=AR over docs/reviews and legacy/reviews:
an add sets the date, a rename (the #682 archive move) carries it to the
new path instead of adding the document again. The "missing" count of
#737 (hp:usage-none) follows the same window. ship findings keep reading
every SHIP-REVIEW document; only the token sum is windowed. Without the
date map (a unit over ready documents) there is no window, as before.
Proof is a temporary git repository with dated commits: a document
outside the window, one inside, an hp:usage-none pair on both sides and
an archive move inside the window; only the inside documents count.
