feat: add official resource sync pipeline

Add the production-facing official update service and bat-official-sync watch CLI for unattended resource synchronization.

Support launcher-resource discovery without installing the launcher, remote marker snapshots, local manifest audit and repair, official seed hash validation, bootstrap caching, richer Addressables coverage, SQLite resource persistence, and FFI JSON helpers.
