Covers what haul is, how to build it, and how to use it.
The build section is deliberately detailed about cgo: haul needs a C compiler
and the platform graphics headers, unlike dial, and cross-compiling needs a
per-target toolchain rather than just GOOS/GOARCH. Documents fyne-cross as the
practical route to Windows and macOS builds.
Claims are limited to what the code actually does — SFTP only, resume within a
session only, and ~/.ssh/config treated as read-only.
