Pull request overview

This PR extends the opalr client to support server-side “file bundle” background tasks when downloading folders and/or encrypted downloads, and adds new helper APIs around file metadata and task cleanup.

Changes:

• Add opal.file_info() to fetch Opal filesystem metadata for a path.
• Add opal.task_delete() and update task docs to include it.
• Update opal.file_download() docs and implementation to use a _file-bundle background task and bump package version to 3.6.0.
