The kiwi parser produces vectorNetwork data in a different format than
the REST API: vertices as {x, y} objects and segments as {start, end}
with nested vertex/tangent properties. The vectorNetworkToSvgPath
converter now detects and handles both formats, fixing icons that
previously rendered as blank colored squares.

Also preserves stroke properties (strokePaints, strokeWeight, strokeCap,
strokeJoin, fillPaints) from raw kiwi nodeChanges that the @grida/refig
factory drops, and renders proper SVG stroke attributes including
linecap, linejoin, fill-rule from winding rules, and overflow:visible
to prevent stroke clipping at viewBox edges.

Preserve textAutoResize from kiwi nodeChanges (dropped by @grida/refig
factory) and use it in figmaToHtml to control text sizing:
- WIDTH_AND_HEIGHT (auto-width): white-space nowrap, no fixed width
- HEIGHT (fixed-width): add 1px buffer for CSS font metric differences

The @grida/refig library sorts Figma node children using
String.localeCompare(), but Figma's fractional index strings
(parentIndex.position) use mixed-case ASCII characters designed for
byte-level comparison. localeCompare is case-insensitive and
alphabetical, producing wrong order (e.g. "i" < "P" alphabetically,
but "P" < "i" in ASCII byte order). This scrambles both z-index for
absolutely-positioned children and visual flow for auto-layout children.

Fix by:
- Preserving kiwi parentIndex.position on each factory node
- Re-sorting the entire _figFile tree after parsing with byte-level
  comparison (< / >) instead of localeCompare
- Using the same corrected comparator in buildDerivedTree for shared
  library component children
