v1.45.4: review of v1.45.3 — R5-1, R5-2

R5-1: the backend signs each path independently and answers successfully with
whatever it managed, skipping (and logging) the rest. The card read any
successful call as 'the batch is done', cleared the backoff for every path in
it, then wrote only the urls that came back — so a path the backend kept
skipping was asked for again on every render, the exact amplification the
backoff was added to stop. A path now counts as signed only when the answer
carries a url for it; the others back off individually, keys that were not
requested are ignored, and onUpdate fires only when a new signature landed.

R5-2: docs/STATUS.md still described main as holding releases up to v1.40.1 and
quoted test counts several releases old, while the version line beside them was
kept current — a handoff reader got a wrong branch model and less coverage than
exists. Branch roles are now accurate, and the counts are gone rather than
corrected: scripts/inventory.mjs (npm run inventory) prints them from the tree,
so there is nothing left to drift.

Tests: three unit cases for empty/partial/foreign-key answers, verified to fail
against a v1.45.3 checkout; a backend test pinning the partial-success contract
by making async_sign_path raise for one path of two.
