Improve anikoto backup search fallback

- prefer the canonical queued title for anikoto-cli backup searches instead of relying only on the ani-cli source query
- retry backup searches with alternate title variants when AniList misses the first lookup
- bump the project version to 0.46.4 and document the fix in the changelog and README
