2. Which behaviors were modified. What was the previous behavior, what is it now, why was it modified, and what possible impacts might there be.
3. What features were added. Why was this function added?
4. Which code was refactored and why was this part of the code refactored?
5. Which functions were optimized and what is the difference before and after the optimization?

Pull request overview

Fixes cloud warm-up file cache downloads to correctly support packed files by using the PackedFileSystem-wrapped filesystem from rowset metadata, and extends regression coverage to run warm-up/cache/tablet-cleanup suites with packed files toggled.

Changes:

• Switch warm-up download paths to use RowsetMeta::fs() (PackedFileSystem-aware) instead of storage_resource->fs.
• Update multiple cloud P0 regression suites to run with enable_packed_file enabled/disabled.
• Add BE config injection for enable_packed_file across the impacted suites.
