fix: verify --platform names uncached data dirs

A platform entry that resolves only through a data directory tree read as missing with no cause on a checkout where data/ was never refreshed, while an online pack build refreshes the trees and packs it. verify_platform now reports the uncached trees and prints them when files are missing.
