Phase 6: Machine profile constraint (PR-10)

End-to-end test that machine constraints are actually enforced. Uses
the PR-10 profile from issue #36.

Files:

Modify: tests/test_pipeline_e2e.py
New: data/test_fixtures/oversized.svg (a design that exceeds the
PR-10 hoop)

Acceptance:

process(oversized.svg, machine_profile="brother_pr10") either:
(a) rejects with a clear error, or (b) scales to fit, depending on
the pipeline's policy. The test asserts on whichever behavior the
pipeline implements; whichever it is, the test exists and pins the
behavior so it doesn't silently change.
A design within the hoop passes through unchanged.
Max thread count constraint: a design with 50 colors, with the
PR-10 profile (10 threads), produces output with ≤ 10 distinct
colors.

Depends on: P1, issue #36 (PR-10 profile exists).

Cross-cutting

All tests use snapshot + tolerance, not byte-exact matches
(raster output is sensitive to numpy/scipy version pins; the
pipeline is deterministic in shape but the bytes can shift).
Tests are run by CI on every PR. Local dev can skip them with
pytest -m "not e2e" for fast iteration.
Total runtime target: < 60 seconds for the full e2e suite. If it
exceeds that, the slowest test gets a pytest.mark.slow and CI
runs it in a separate job.
