Pull request overview

This PR fixes cloud warm-up/file-cache downloads to correctly support packed files by switching download I/O to use the RowsetMeta-provided filesystem wrapper, and updates cloud regression suites to exercise packed-file mode.

Changes:

• Use RowsetMeta::fs() / rowset_meta->fs() for warm-up and file-cache downloads so segment/index paths resolve correctly when packed files are used.
• Update multiple cloud regression suites to toggle enable_packed_file at runtime to cover both packed/non-packed scenarios.
