rob thijssen 60176e7c2e ci: monotonic prerelease versions + serialize CI on shared runner
Two CI hygiene fixes uncovered while validating against the live fleet.

1. Same-day prerelease packages were being ordered by RPM-vercmp's
   alpha-vs-digit precedence on the git SHA fragment, not by commit
   chronology. With release stamps like "0.1.${YYYYMMDD}git${SHA}",
   two commits on the same day produce the same numeric prefix and
   rpmvercmp falls back to comparing the alphanumeric SHA suffixes,
   where digit-leading SHAs are ranked above alpha-leading ones —
   completely unrelated to which commit landed first. Verified with
   rpmdev-vercmp:
     gitabc1234 < gitdef5678   (old scheme — purely lexicographic)
   Bumping the timestamp prefix to second-precision (%Y%m%d%H%M%S)
   makes the numeric prefix strictly monotonic for any chronologically-
   ordered commits, so the SHA fragment becomes a debug identifier
   only — never participates in version ordering.

2. ci.yml and build-prerelease.yml both target the `rust` runner label
   and both auto-trigger on push to main. The act-based runner reuses
   /root/.cache/act/<hash>/hostexecutor/ across concurrent jobs, so
   ci.yml's clippy and build-prerelease.yml's build-cortex were racing
   each other's checkout/cleanup steps and corrupting in-flight
   compile artifacts. Real fix is in gongfoo; workflow-level workaround
   is a shared concurrency group with cancel-in-progress=false so the
   two workflows queue sequentially on the same ref.

# Prebuilt-binary spec for helexa-neuron flavoured by CUDA compute capability.
#
# Unlike helexa-neuron.spec (which builds from source via cargo), this
# spec wraps a pre-built `neuron-{flavour}` binary produced by an
# upstream CI job and packages it for rpm.lair.cafe. The %build phase
# is a no-op.
#
# Required defines at rpmbuild time:
# neuron_version e.g. "0.1.16"
# neuron_flavour e.g. "ada", "blackwell" — matches the CI build
# matrix's compute_cap label.
# neuron_prerelease e.g. "0.1.20260518140530.gitabcdef0"
# ^^^^^^^^^^^^^^^^^^ ^^^^^^^^
# commit time (sec) commit sha
# (used as Release; the timestamp prefix
# keeps same-day builds strictly ordered.)
#
# One flavour can be installed at a time on a given host; flavour
# packages Conflict with each other.

%description
Neuron is the per-node daemon for cortex inference clusters. It
discovers local GPU hardware via nvidia-smi, runs in-process
inference via huggingface/candle, and exposes an HTTP API for model
lifecycle management (load, unload, list, inference endpoint).
This is the %{neuron_flavour} flavour, built for that CUDA compute
capability. Install the flavour matching the GPUs on this host.
