Updating RomM

This package intentionally begins with RomM 3.5.0 so the StartOS wrapper can be validated independently from an application upgrade.

For a future update:

Read the RomM release and database migration notes.
Verify the image tag and both amd64 and arm64 manifests.
Pin the new multi-architecture digest in startos/manifest/index.ts.
Reinspect the entrypoint, ports, volumes, users, and environment variables.
Update startos/versions/current.ts; add a historical node only for an explicit package migration.
Update README and instructions for user-visible behavior.
Test install, upgrade, login, scan, restart, backup, and restore on StartOS.

Do not restore compatibility with the abandoned StartOS 0.3 wrapper.
