Phase 1: SVG → DST round trip

The core happy path. The original MVP that issue #2 (DST fallback
produces corrupt files) regressed. This test would have caught it.

Files:

New: tests/test_pipeline_e2e.py (test file)
New: data/test_fixtures/simple_square.svg (a known SVG)

Acceptance:

process(simple_square.svg, output_format="dst") produces a valid
DST file (header check: starts with the correct DST magic; stitch
count in the expected range; no truncated bytes).
The test runs in CI on every PR.

Why first: if this fails, the basic pipeline is broken and all
other tests are noise. Land this first to establish the test infra
works.
