Do not verify emit source hash for coverage

Editor assessment

A quietly excellent fix header: fix(coverage) with 'do not verify emit source hash for coverage' is imperative, precise about both the skipped check and the affected command, and comfortably within length. The scope maps to a real user-facing subcommand, so changelog filtering will place this correctly, and the fix type implies a patch bump. Skipping hash verification is the kind of change that invites a why — presumably stale emit artifacts caused spurious failures — but a one-line body would have settled it. As it stands the subject is clear enough that the omission is forgivable. Solid, disciplined work.
