123f692203 fix(rpm): drop %attr(,,user) on config files to avoid dnf silent filter
Some checks failed

Using %attr(,,cortex) / %attr(,,neuron) on config files caused rpm's
auto-dep-generator to emit Requires: user(name) and group(name) on
each package. When those Requires couldn't be resolved — whether due
to sysusers Provides mismatches, missing GPG keys, or dnf5 cache
state — dnf5 silently filtered the package out of the candidate set
and reported "Nothing to do" rather than an unsatisfied-dep error.

Adopt the pattern that already works reliably across our infra
(grenade/monsoon): ship config files as default root:root with 0644
perms, don't declare user/group ownership in the rpm file list.
systemd-sysusers still creates the service user via the shipped
sysusers.d file; the service drops to that user at runtime via the
User= directive in the unit.

This removes the user(cortex)/user(neuron) Requires entirely, which
is the root cause of the dnf5 filtering. File permission tightening
can be reintroduced later — either via a separate secrets file with
different mode bits, or by moving secret material to /var/lib/<svc>/
where the service drop-privileges account already has write access.

neuron and cortex are independent packages installable on different
hosts. Having neuron run under a 'cortex' system user implied a
shared identity that doesn't exist. Give neuron its own user/group.

- New data/neuron-sysusers.conf declares the neuron user/group with
  home /var/lib/neuron.
- systemd unit User/Group changed to neuron.
- Spec file attrs, explicit Provides, and %sysusers_create_compat
  updated to reference the neuron user.

The neuron package was shipping its config at /etc/cortex/neuron.toml,
which implied a shared config directory between two independent
packages. Move to /etc/neuron/neuron.toml — neuron owns its own etc
dir, consistent with its own /usr/lib/sysusers.d/neuron.conf and
/usr/lib/systemd/system/neuron.service. Updated the systemd unit's
ExecStart path and the example toml header to match.

Replace the in-repo .gitea/scripts/copr-build.sh and per-job
copr-cli configuration with the shared composite action at
https://git.lair.cafe/actions/copr-publish@v1. Behaviour is
identical — submit, watch, dump per-chroot logs — but the logic
now lives in a single place that other projects can consume.

Removes the actions/checkout step from both COPR jobs since the
build script is no longer local to this repo.

dnf5 was silently rejecting neuron-0.1.3 with "Nothing to do" because
it had an unresolvable Requires. Inspection showed:

  Requires: user(cortex)               ← unversioned
  Provides: user(cortex) = <base64>    ← versioned only, no unversioned

rpm's sysusers provides-generator only emits the unversioned user()
provide when the u-line is minimal. Our sysusers.conf specifies GECOS,
home dir, and shell, which pushes the generator to versioned-only.
The matching Requires (auto-generated from %attr(,,cortex) on config
files) is unversioned, so resolution failed silently.

Explicitly declare Provides: user(cortex) and Provides: group(cortex)
to guarantee the unversioned forms exist. group(cortex) was already
emitted unversioned but adding it for symmetry and to protect against
future generator changes.

5c7d63c658 ci: dump COPR per-chroot build logs to CI output
Previously the COPR publish steps only surfaced copr-cli's status
updates (pending/importing/running). When a build failed, diagnosing
required clicking through to the COPR web UI. Now we submit with
--nowait, watch the build, then use copr-cli download-build to fetch
each chroot's builder-live.log and cat them as collapsible ::group::
blocks in the CI output.

Logic is factored into .gitea/scripts/copr-build.sh so cortex and
neuron jobs share it. Both COPR jobs now check out the repo to access
the script.

cortex-gateway.conf/cortex-neuron.conf implied a hierarchy or coupling
that doesn't exist — cortex and neuron are independent packages.
Each package's sysusers.d file now matches the package name:
cortex ships cortex.conf, neuron ships neuron.conf. Content is still
identical (both create the cortex system user/group), and filenames
remain distinct so the packages can coinstall.

209150771e fix(rpm): use sysusers.d for cortex user/group creation
Both packages set %attr(...,cortex) on their config files, which
caused RPM's auto-dep-generator to emit Requires: group(cortex) /
user(cortex). The %pre scriptlets that actually created the group
ran too late — dnf rejected neuron installation on hosts without
cortex because nothing Provided group(cortex).

Switch to systemd-sysusers declarative user creation: each package
ships its own named sysusers.d file (cortex-gateway.conf and
cortex-neuron.conf — different names so both packages can coinstall)
with identical content defining the cortex user/group. RPM's
user/group dep generator now emits Provides: user(cortex) and
Provides: group(cortex) automatically from the sysusers.d files,
satisfying the auto-generated Requires. Either package installs
standalone; both can coinstall on the gateway host if desired.

Also added Requires: systemd since %sysusers_create_compat depends
on systemd-sysusers being present on the target.
