feat(desktop): mac zip auto-update

+// Build the D1 upsert SQL for a desktop release from the files in a directory.
+//
+// Each mac release has TWO artifacts that map to a SINGLE D1 row:
+//   - <name>-<arch>.dmg  -> manual download   (filename / size / sha512)
+//   - <name>-<arch>.zip  -> auto-update        (update_filename / update_size /
+//                                                update_sha512)
+// electron-updater's MacUpdater can only consume a zip, never a dmg, so the
+// feed serves the zip while the website serves the dmg. Windows has only the
+// .exe (stored in the main columns; it's both the download and the update).
+//
+// We emit ONE `INSERT OR REPLACE` per (version, platform) carrying BOTH halves,
+// because two replaces on the same primary key would drop whichever came first.
+//
+// Usage:
+//   node register-releases.mjs --dir dist --version 1.2.0 \
+//        --sql out.sql [--latest] 
+//
+//   --latest  mark these rows is_latest=1 AND clear the previous latest for
+//             each platform (used by the publish/promote workflow). Without it
+//             rows are written unpublished (is_latest=0) — the build stage.
+//
+// sha512 is base64 (the exact format electron-updater validates).
