Unit tests (29 new in tests/tests.cpp): - str::eq() and str::startswith() char* nullptr safety - str::from() u64/s64/int suffix parsing (K/M/G/T, overflow, invalid) - num::humanize() byte formatting (0, 512, 1K, 1M, 1G, 1T, non-exact) - RmdirErr priority error accumulation (ENOTEMPTY/EEXIST override rules) - HashSet inline-to-heap growth, empty string, and large insertion - fs::inode algorithm switching (valid/invalid names, passthrough raw ino, distinct inodes across algorithms) - RND::rand64() bounds (range, max, shrink_to_rand_elem) - Branches::Impl copy and move assignment re-links default_minfreespace Integration tests (5 new in tests/): - TEST_policy_lup: LUP policy create and search - TEST_rmdir_enotempty_priority: rmdir returns ENOTEMPTY for non-empty dirs - TEST_open_after_unlink: read/write via fd after unlink - TEST_api_xattr: mergerfs xattr API (fullpath, relpath, basepath, allpaths) - TEST_movefile_enospc: moveonenospc configuration round-trip Also: remove xattr nosys checks from TEST_cfg_xattr_modes, reformat integration test scripts to use temp_dir/cleanup_dir helpers, and minor parameter alignment changes in fuse_getxattr, fuse_init, fuse_rename.
