MERGE ALL EARLIER PRs FIRST -- chore: bump dlio-benchmark to DLIO #39; version 3.0.25 -> 3.0.26

[FileSystemGuy]

Summary

Bump dlio-benchmark pin to pick up DLIO PR #39 (merged f16fe43), which resolves #567, and roll the project version 3.0.25 → 3.0.26.

• DLIO pin: 252a54b1 → f16fe43f. The fix in Single host reportgen not working? #39 broadens the _LocalFSIterableMixin O_DIRECT gate so it triggers on either storage_options.uri_scheme == "direct" (canonical signal — what direct_fs validation produces) or the legacy storage_options.storage_library == "direct". Before the fix the two halves of DLIO required different storage_library values and --o-direct for local NPZ / NPY / JPEG always crashed in the warmup batch with FileNotFoundError: 'direct:///mnt/…/foo.npz'.
• Net effect for mlpstorage: --o-direct for UNet3D / ResNet / any local NPZ-NPY-JPEG workload now reaches the s3dlio O_DIRECT engine instead of feeding direct:// URIs to plain open().
• uv.lock: regenerated via uv lock --upgrade-package dlio-benchmark. Same 108 packages resolve; only the dlio-benchmark source SHA moves.
• Pin-history comment at pyproject.toml:131-148 updated with a new line for DLIO Single host reportgen not working? #39 / storage --o-direct / storage_type=direct_fs crashes on local NPZ/NPY/JPEG — storage_library sentinel disagreement between config validation ("s3dlio") and the iterable reader ("direct") #567 (most-recent-first ordering).

Test plan

• uv run pytest tests/unit -q → 2290 passed. No regressions.
• test_version_matches_pyproject and test_dist_name_matches_pyproject pass at the new version.
• uv lock resolves cleanly with no other dependency churn.
• On-cluster: reporter's mlcommons/storage#567 reproducer (mlpstorage … training unet3d run file --o-direct …) should now train past warmup. Worth confirming on the lab cluster before tagging a release.

Closes / fixes (downstream)

• Closes --o-direct / storage_type=direct_fs crashes on local NPZ/NPY/JPEG — storage_library sentinel disagreement between config validation ("s3dlio") and the iterable reader ("direct") #567 — fix lives in DLIO Single host reportgen not working? #39; this PR is the downstream pin bump that makes 3.0.26 carry the fix.

Notes

• This is a clean version bump on top of main (currently includes the recent CAP-01 capacity gate fails for training/checkpointing in object (S3) mode — statvfs runs on the s3:// URI #568 CAP-01 object-mode fix).
• Independent from the still-open fix(#566,#569): CAP-02 shared-FS probe works on FUSE; preserve scp basename #577 (CAP-02 / scp staging fixes for CAP-02 shared-FS probe rejects all multi-host DAOS/FUSE filesystems due to spurious st_dev comparison #566 + Cluster collector remote staging hardcodes the destination filename, breaking the multi-host CAP-02 shared-FS probe #569) — fix(#566,#569): CAP-02 shared-FS probe works on FUSE; preserve scp basename #577 will rebase cleanly onto main regardless of merge order.
