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.

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.

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.

COPR build failed on openssl-sys because openssl headers were not
available in the mock chroot. Adding:
- pkgconfig(openssl): fixes the immediate openssl-sys failure.
Kept as a build dep because we plan to add optional mTLS between
cortex and neuron, which requires native-tls/openssl at build time.
- cmake, gcc-c++: aws-lc-sys (pulled via rustls) compiles libcrypto
via cmake and includes C++ sources. Would be the next failure after
openssl.
- perl-interpreter: catchall for -sys crate build scripts.

Three complementary tweaks to close the gap sccache alone can't:
- CARGO_INCREMENTAL=0: reclaims the 17 incremental-mode cache misses
per run and prevents cargo from writing incremental fingerprints
that defeat sccache. Incremental mode is useless in CI anyway since
each run starts from scratch.
- actions/cache for ~/.cargo and target/: sidesteps sccache's
structural limits (proc-macro non-cacheables, clippy-vs-rustc
separate namespaces) by caching the whole build output keyed on
Cargo.lock. Also caches ~/.cargo/bin so the installed sccache
binary survives between runs.
- Drop the separate 'cargo build' step: 'cargo test --workspace'
builds everything anyway, so the standalone build was a full
redundant workspace compile pass.

The workflow-level env set RUSTC_WRAPPER=sccache for every step,
including the install step itself. cargo install sccache then
tried to invoke `sccache rustc -vV` to detect the toolchain before
sccache existed on PATH, failing with "No such file or directory".
Override RUSTC_WRAPPER to empty on the install step so cargo uses
rustc directly; subsequent steps still inherit the wrapper.

The distro sccache package lacks S3 support. Install from cargo
with --features s3 if the existing binary can't connect to the
S3 backend. Skips install if already present and working.

All Rust compilation steps now use sccache backed by MinIO S3
at caveman.kosherinata.internal:9000. Credentials via repo secrets
SCCACHE_S3_ACCESS_KEY and SCCACHE_S3_SECRET_KEY. Cache is shared
across all bare metal runners.

Replace NodeConfig (static vram_mb, pinned) with NeuronEndpoint.
Hardware discovery and model pinning now come from neuron API and
models.toml catalogue respectively.
- config.rs: nodes -> neurons, add models_config path
- catalogue.rs: ModelProfile with pinned_on, ModelCatalogue
- poller.rs: poll neuron GET /models (ModelInfo format)
- router.rs: resolve inference endpoint via neuron GET /models/{id}/endpoint
- evictor.rs: call neuron POST /models/unload
- node.rs: remove vram_mb, pinned fields (come from discovery/catalogue)
- All 22 gateway tests updated to mock neuron API
- Remove MistralModelsResponse, ModelLifecycleRequest (no longer needed)

Extract public poll_once() from poll_loop() for testability.

Confirms the existing proxy streams SSE chunks incrementally:
- 5-chunk test with 50ms delays verifies time spread between first
and last chunk arrival (not buffered)
- Verifies data: [DONE] terminator is forwarded
No src/ changes needed — Body::from_stream(bytes_stream()) already
handles SSE correctly.
