Pull request overview

This PR refactors and reorganizes the test suite by moving tests under anyplotlib/tests, consolidating coverage areas into more structured modules (layouts/interactive/documentation/benchmarks/plots), and adding/relocating baseline assets to support visual regression testing.

Changes:

• Move/merge legacy tests/ modules into a package-scoped test tree (anyplotlib/tests/...) and update pytest discovery to match.
• Add new structured test modules for Plot3D, markers, documentation bridge/scraper/push-hook, and pure-Python benchmarks.
• Introduce/relocate PNG baseline assets and PNG encode/decode utilities for visual regression testing.

pyproject.toml:55

• Since tests were moved under anyplotlib/tests, the coverage config now treats them as in-scope code (source = ["anyplotlib"]) but omit = ["tests/*", ...] no longer matches. This will skew coverage (and may fail CI) unless you also omit anyplotlib/tests/* (and likely anyplotlib/tests/baselines/*). Separately, hatch will now package anyplotlib/tests into the wheel via packages = ["anyplotlib"]; if that’s not intended, add an explicit exclude to avoid shipping large baseline PNGs.
  anyplotlib/tests/test_layouts/test_visual.py:42
• BASELINES points to anyplotlib/tests/test_layouts/baselines, but the baseline PNGs added in this PR live under anyplotlib/tests/baselines. As written, these visual regression tests will always hit the if not path.exists(): pytest.skip(...) path and won’t validate rendering in CI. Update the baseline directory (or move the PNGs) so the tests actually exercise the golden images.
  anyplotlib/tests/test_layouts/test_inset.py:282
• BASELINES points to anyplotlib/tests/test_layouts/baselines, but the inset baseline PNGs in this PR are under anyplotlib/tests/baselines. With the current path, all visual inset checks will be skipped due to missing baselines. Point BASELINES at the shared baselines directory (or relocate the PNGs) so these regression tests run.
