Krzysztof kuhy Rudnicki 4326ea421b CI: install rsvg-convert on GitHub Actions runners (Phase 0 fix)
ubuntu-latest lacks librsvg2-bin, so test_render_writes_png was
skipped in CI, leaving vector.py:156 uncovered and both Pre-commit
checks and Python tests red at 99.98% (1 line miss). Installing the
real dependency lets the test run instead of excluding the line.

# The runner image carried 0.9.0 while developer machines have 0.11.0
# from pacman, and the shellcheck hook is `language: system` -- so it
# used whichever binary happened to be on PATH. The two versions
# disagree (0.11.0 demoted SC2002 and several SC2015/SC2119 cases as
# noise), which meant a commit could pass every local check and still
# fail CI on findings the developer could not reproduce. That is exactly
# what kept this workflow red from b83ce5d onward.
#
# Keep SHELLCHECK_VERSION in step with the version developers install;
# the verification below fails loudly rather than silently drifting.
