atlas 4423da4899 deploy: move the forge CI runner toggle out of swarm
Last of the swarm.* -> deploy.* moves for the enable-shaped options.
Whether this host also runs the CI runner is a per-machine decision, so
it was sitting in the namespace that has to be identical swarm-wide.

Renames all five options, not just enable: name, concurrency, labels and
package all describe the runner THIS host would run, and leaving them
behind would keep the original defect for four more options. One rename
entry each, because ci is a plain attrset rather than a submodule type,
so there is no parent path to rename in one go.

deploy.forgejo is the name deploy.nix's own header already specifies,
including this exact case -- "ci (does this host run the runner too) is
exactly that shape". It is the only entry with no enable: the forge is
not optional, it deploys with hyperhive itself, so running the runner is
the only deployment decision it has.

Also fixes hive-c0re/src/forge/ci_runner.rs, whose doc comment named
services.hyperhive.forge.ci.enable -- missing the swarm. segment, so it
had never resolved to a real option.

# "What does THIS host deploy?"
#
# Separated from `services.hyperhive.swarm.*` because those are two
# different kinds of fact and only one of them varies per machine:
#
# swarm.* — swarm-wide truth. The swarm's name, domain, hives, peers,
# CA, and where each service lives. **Identical on every
# host**, byte for byte; a hive needs all of it to be a
# *client* of the swarm.
# deploy.* — this machine's deployment decisions. Necessarily different
# on every host, because that is what a deployment is.
#
# The `enable` toggles used to live under `swarm.*`, which made the
# namespace that is supposed to be identical everywhere carry the one
# thing that must differ.
#
# Flat and named for the thing deployed — `deploy.forgejo`, not
# `deploy.swarmServices.forgejo`: grouping by "swarm service" re-encodes
# the service-side taxonomy into a layer that does not care about it.
#
# ⚠️ Each entry is an attrset with an `enable`, not a bare bool, so a
# service that grows a second *deployment* decision has somewhere to put
# it — `deploy.forgejo = { enable; ci; }` is then an ordinary addition
# rather than a migration. `ci` ("does this host run the runner too") is
# exactly that shape, and a bare bool leaves it unrepresentable.
#
# ⚠️ The renames below are deliberately in this one file rather than
# spread across the service modules, so the whole move has a single home
# and a single file to delete when the deprecation window closes — the
# shape ./swarm-peers-removed.nix already uses.
