fix(signals): a derived store's propagated error reaches its readers once (#4463)

* fix(signals): a derived store's propagated error reaches its readers once

propagateStatus handed the derive's family a status without its error, so
errorFamily's same-error skip could not apply and a sync derive over a sync
memo re-ran its reader's error arm twice in one flush (#4457 review).

* chore(size): re-measure over next @ 131ceb8c; type the family status error

Raise the base + router and compiled hydrating caps (brotli layout from
+2 B minified) and give StoreFamily.st its error parameter.
