* Restore colorbar frame handling

This restores frame/frameon as a reliable public colorbar option again. Outer colorbars now treat it as a backwards-compatible alias for outline, while inset colorbars stop storing raw booleans as frame artists and therefore no longer crash during layout reflow when the frame is disabled.

The change also adds regression tests for both the outer and inset paths.

Closes #609

* Clarify colorbar frame defaults in docs

* Preserve geometry hatch styles in legend proxies

Cartopy geometry artists created with add_geometries() were keeping hatch on the plotted FeatureArtist but dropping it when UltraPlot built the PathPatch legend proxy. This updates the geometry legend handler to copy common patch-style properties more generically, including hatch, while keeping the existing joinstyle fallback.

A regression test now covers add_geometries(..., hatch='/', label=...) so semantic geometry legends preserve the plotted hatch pattern.

Closes #611

* Generalize geometry legend patch style copying

* Document geometry legend style-copy rationale

* Black

* Document geometry legend proxy limitations

* Update ultraplot/legend.py
