This pull request adds comprehensive documentation detailing the planned three-store architecture (containers-storage, composefs, and ostree) and its use of reflinks (FICLONE) for zero-copy operations. It updates several source files with module-level rustdocs and expands the experimental unified storage documentation. One issue was identified in the rustdoc comments where a broken intra-doc link to a non-existent method Storage::reflinks_supported would cause a compilation error.
Update the experimental-unified-storage doc and add rustdocs to describe the planned upcoming three-store architecture (containers-storage -> composefs -> ostree). This will eliminate tar serialization and share physical disk blocks. Assisted-by: OpenCode (claude-sonnet-4-6) Signed-off-by: Colin Walters <walters@verbum.org>
