feat(cli): sync folders with remote paths

- Store synced folder locations in file_path instead of embedding them in file names.
- Add ignore rules from .nanoshareignore and repeatable sync --ignore flags.
- Adopt existing remote files only after SHA-256 verification.
- Move adopted remotes with metadata updates instead of uploading duplicates.
- Bump NanoShare to 1.23.0 and the standalone CLI to 0.2.0.
