Valentin KleinandClaude Opus 5.5 d433112f1e Draw hatch island styles, backgrounds, two-colour gradients and file pattern definitions (fixes #289, fixes #290) (#302) ...

- Island detection style (group 75) picks the loops that take part: outer keeps the
  outermost loops and their first islands, ignore only the outermost loops.
- A pattern hatch's background colour is filled under its pattern lines.
- Gradients blend colour 1 to colour 2 (LINEAR, CYLINDER, CURVED, SPHERICAL,
  HEMISPHERICAL and the INV forms) along their angle, shifted when not centred, drawn as
  bounded colour steps; ByLayer / ByBlock gradient colours resolve to the hatch's layer /
  block colour instead of colour 7.
- DXF HATCH pattern definition lines (78, 53, 43-46, 79, 49) of a pattern the library
  doesn't define are kept on the hatch (new `patternLines` field), drawn and written back;
  hostile counts are capped.
