Haskell workspace manager is not published

Haskell has no published libtmux workspace manager. The planned library and command-line tool will live in a separate Cabal package and use the core library to operate on tmux.

There is no workspace package to install, loader command to run, or workspace API reference yet. The current public core provides typed IDs, checked dimensions and indices, and tmux-version admission.

Start with the core library and its tested values example. Read the implementation status for the available capabilities and remaining work.
