Antonio SJ Musumeci 84e4cdeb7e make all integration tests self-contained with ephemeral mounts
- Add mergerfs_mount() context manager in posix_parity.py that creates
  temporary branch dirs in tests/.test_tmp/, mounts an ephemeral mergerfs
  instance, and cleans up after use.
- Add find_mergerfs(), find_fusermount(), mount_mergerfs(), unmount_mergerfs()
  helpers.
- Update run-tests to invoke each TEST_* script without a mountpoint arg.
- Update README.md to document the new `python3 tests/run-tests` invocation.
- Fix 44 tests to use mergerfs_mount() instead of expecting a pre-mounted path.
- Add tempfile import to 10 tests that were missing it.
- Fix TEST_mount_lifecycle to use mergerfs_mount() context manager.
- Fix TEST_posix_tmpfile missing join import.
- Fix TEST_cfg_xattr_modes error message framing (no "(known bug)").
- Fix TEST_posix_copy_file_range: loop-copy full size, compare st_size and
  SHA256 hash; add NativeTmp for space management; route native temp to
  tests/.test_tmp/ to avoid ENOSPC on /tmp.
- Fix TEST_posix_getattr_fgetattr: st_cmp skips st_size for dirs; add
  compare_ino param for safe inode comparison when inodecalc=passthrough.
- Fix TEST_unlink_rename, TEST_use_* tests: namespace cleanup, consistent
  variable naming, None check for cmpfunc.
- Fix TEST_readlink_semantics: remove type annotations to support older
  Python; wrap in mergerfs_mount() try/except.
- Add flush=True to run-tests print so test names show immediately.
