Add disable/enable methods to AssetSeeder to respect --disable-assets-autoscan flag

- Added disable(), enable(), and is_disabled() methods to AssetSeeder
- start() now checks is_disabled() and returns early if disabled
- Updated main.py to call asset_seeder.disable() when CLI flag is set
- Fixes bypass where /object_info would trigger scans regardless of flag
