Novij Storage
P30-P32 package/sync foundation
- Added read-only sync/status foundation: `/sync/status`, `/sync/peers`,
`/sync/inventory`, `/sync/block/{block_id}/chunks`, `/sync/conflicts`, `/sync/lag`.
- Added `novij-storagectl` for audit dry-run, safe pull-missing, peer visibility,
install auth, and first-run setup.
- Added Debian packaging configuration for `novij-storage`.
- Added package smoke and package-site publish flow for `packages.novij.tech/storage`.
- Package services require owner-signed install authorization before startup.
- `novij-storage-sync.timer` runs missing-only sync with caps and no overwrite/delete.
Live write/append, fake billing source, and payout settlement were not added.
