fix: count an uncached release asset as fetched

verify resolved offline, so a release asset absent from bios/ and the
cache read as missing while an online build fetched and packed it. verify
now reads the database record of the registered path and counts such a
declaration present, listed as fetched at build time. --offline keeps the
old count, and the offline pipeline passes it to its verify step.
