chore: bump version 0.2.72 (#892)

Release 0.2.72 with the S3 credential refresh reliability work (#891)
and the numpy deserialize copy fix (#887).

Also corrects the changelog: the multi-node FullShuffle fix and the
max_cache_size change were left under [unreleased] by #886, but #886 is
the commit v0.2.71 was tagged at, so they shipped in 0.2.71. Moved them
into that section and added the missing entry for #887.

…ly (#886)

* feat(streaming): pin node shards when they fit, else reshuffle globally

Keep unique chunks on a node across epochs when they fit in cache, and default max_cache_size to a conservative slice of free disk so checkpoints still have room.

* docs: keep shuffle and cache-size notes under unreleased

Co-authored-by: Cursor <cursoragent@cursor.com>

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* tests: drop unused shuffle expected list

* fix(streaming): cache shuffle chunk count and drop duplicate resume line

Co-authored-by: Cursor <cursoragent@cursor.com>

* tests: pin emulate-S3 cache size so CI does not evict under mmap

Co-authored-by: Cursor <cursoragent@cursor.com>

* feat(streaming): accept max_cache_size as size or free-disk fraction

None still uses 75% of free disk with a 50GB reserve. "100G" pins bytes;
0.90 uses that share of currently free space.
