• fix(glyphs): remove orphaned render artists on repeated plot()/animate() calls (#211)

• • Track each Axes' prior render artists via a shared marker so a second
    plot()/animate() call — same glyph instance, or a different glyph
    sharing the Axes via ax=/fig= — removes them instead of leaving
    them attached and undriven.
  • Extend cleanup to ArrayGlyph, MeshGlyph, StatisticalGlyph, and
    VectorGlyph: colorbars, frame-label text, point/cell-value overlays,
    and streamplot arrowheads (never actually attached via the returned
    collection, so removed by diffing ax.patches instead).
  • Defer cleanup until after each call's own input validation succeeds,
    so a failed call (e.g. an invalid color_scale, or a mismatched color
    list) no longer destroys a valid prior render before propagating its
    exception.
  • Tolerate an artist already partially removed by ax.clear() or a
    prior apply_style() call instead of crashing on the second removal
    attempt.
  • Add direct unit tests for the shared cleanup helpers and regression
    tests covering same-instance repeats, cross-glyph shared axes, and
    validation-failure paths across all four glyph classes.

  Closes #210
