fly.toml points Fly directly at ghcr.io/fabro-sh/fabro:nightly (no
builder step), pins internal_port to 32276 since Fly does not inject
$PORT, declares a Volume mount at /storage, and disables autostop so
the run queue stays live under no HTTP traffic.
Replaces the deploy-fly-io.mdx stub with a CLI-first walkthrough
covering volume creation, secrets, dev token retrieval, and the
single-Machine / single-Volume caveats that apply to Fabro.
