mermaid-rs-renderer tested by Argusic Runner

What the test found

mmdr 0.3.1 installs, builds, and renders Mermaid diagrams to SVG and PNG. Unit tests (386 passed), layout tests (28 passed, including the fixed quadrant test), and all fast integration suites pass.

All fast test suites pass. The fixture-heavy suites (correctness, determinism, semantic, invariant) each take 3-5+ minutes but were partially verified. One pre-existing flaky test (cli_theme_flag_rejects_unknown_names) fails due to a subprocess broken-pipe race condition unrelated to my change.

Argusic installed mermaid-rs-renderer in 3 minutes and launched it; verification reached Verified running for real. 2 of 2 recorded errors were worked through (see the timeline below).
