feat(editor): add --validate-project-checksum for cross-platform verification

Browse source 
Closes the emit/verify loop for --export-project-checksum natively, so
Windows runners and CI containers without coreutils' sha256sum can
still validate PROJECT_SHA256SUMS. Re-hashes every file listed in the
manifest, reports ok/missing/mismatched counts, and exits 1 on any
failure with a per-file failure list.

Verified all three paths: success (9 ok / exit 0), missing file
(1 missing / exit 1), mismatched hash (2 mismatched / exit 1).
Brings command count to 171.
