Pure structural split of src/shared/file_receive.c into focused translation units behind the unchanged file_receive.h facade: - file_save.c : save-to-disk, special nodes, --delay-updates staging - incremental_check.c : xattr/delta/basis/fuzzy receive + check state machine - delete_commit.c : manifest receive + delete budget walkers - file_receive.c : wire receive dispatch + deferred dir metadata The shared receive_file_xattrs helper and MAX_FILE_DATA_SIZE are declared in incremental_check.h. file_save_to_disk_full_ex is decomposed into static helpers (validation, special dispatch, dir/symlink creation, path resolution, pre-write policies, data install) routed through one cleanup epilogue. No behavior change.
