Function restore 

pub fn restore(paths: &Paths, dry_run: bool) -> Result<RestoreOutcome>

Restore everything in the ledger.

For each entry: rename suspect back to original (overwriting any stub that lived there), then drop the entry. Entries whose suspect file is missing are surfaced as SuspectMissing but don’t abort the rest. On success the ledger file is removed.

Errors

• crate::Error::Io on rename / write / delete failure.
• crate::Error::Json on ledger parse failure.
