`.totalFileAllocatedSizeKey` returns nil for directories on Darwin but
on Linux it returns `st_blocks * st_blksize` (4 KB each) in Foundation.
The empty-store test summed three directory inodes on Linux and failed
with `#expect(size == 0)`. This change adds filter on the enumerator to
regular files only so the totals are content-only and will work for both
Darwin and Linux.
This PR adds `totalAllocatedSize()` to the `ContentStore` protocol so it
can be used to get the on-disk footprint without reaching past the
abstraction. `LocalContentStore` implements it by walking its base path,
covering both committed blobs and active ingest sessions.
