Allow for assignable address

Line 199 in 141f136

server_address = ("127.0.0.1", port)

My currently development setup is to ssh into a development system this means that the ip_address or host needs to be assignable.

Current workaround -

Build only
Then run uv run python -m http.server 8000 --bind 0.0.0.0 --directory output
