Wire L1 render conformance tests to the renderer (R-NET-01, R-NET-05/06/07)

Implements the two L1 rendering tests that were failing scaffolds:
- egress-class-render (R-NET-05/06/07): renders vpn + internet fixtures, diffs each
  against a committed golden, asserts the vpn steering label is present on vpn and
  absent on internet (fail-closed), and that flipping the class changes ONLY the
  egress path (R-NET-07). This fixes the --requirements R-NET-05 merge gate.
- default-deny-baseline-render (R-NET-01): asserts every render carries the
  namespaced default-deny baseline, shaped deny-all + both directions.

Each test carries a pure-offline render-check.sh (renderer + golden diff, no
cluster). run.sh runs L1 render checks offline and emits a REAL pass/fail JUnit
(docs/14: L1 rendering assertions run in CI without a cluster) instead of skipping
L1 with the cluster-gated layers; the chainsaw-test.yaml wrappers invoke the same
render-check.sh so an in-cluster run executes the identical assertion.

+"""Run the L1 *rendering* conformance checks OFFLINE (no cluster) and emit JUnit.
+
+docs/14: "L1 rendering assertions run in CI without a cluster." L1 verifies the
+ServiceDefinition -> rendered-resources mapping against golden expectations; unlike L2/L3
+it needs no live cluster. Each l1-rendering test dir carries a `render-check.sh` (renderer
++ golden diff + structural asserts). run.sh invokes this for `--layer l1` so those tests
+report a REAL pass/fail instead of being skipped with the cluster-gated layers.
+
+Pure standard library (matches the harness's no-pip-dependency posture); the render checks
+themselves shell out to catalog/render.py (the renderer's PyYAML dependency lives there).
+
+Usage: run_l1_offline.py --junit <out.xml> [--label-prefix P] <test-dir> [<test-dir> ...]
+Exit 0 iff every selected render check passes.
