chore(deploy): add haskelseed Alpine startup scripts

OpenRC init script + RunDevServer env wrapper for the haskelseed build VM
(Alpine 3.23, GHC 9.10.3, IHP 1.5). IHP DevServer binds to 127.0.0.1:8000
so socat forwards 0.0.0.0:8080 → 127.0.0.1:8000 for external access.

Deploy steps are documented in the file headers.
