Commit Message

feat: improve writer with programmatic API, fix bugs, add round-trip tests

Fix permission bits to preserve setuid/setgid/sticky using modeToUnix().
Fix directory size to use squashfs +3 convention for unsquashfs compat.
Fix empty directory handling (no fake header).
Fix device number serialization (was hardcoded to 0).
Add reader support for special inode types 4-14 (devices, fifos, sockets).

Add programmatic writer API: AddFile, AddDirectory, AddSymlink, AddDevice,
AddFifo, AddSocket, SetOwner, SetModTime with auto-creation of intermediate
directories.

Add comprehensive round-trip tests covering permissions, ownership,
timestamps, symlinks, devices, fifos, sockets, and all compression types
(GZip, ZSTD, XZ). All tests cross-validated with unsquashfs.

Install squashfs-tools in CI for unsquashfs cross-validation.
