The drawing-card feature batch (icon/image/compare/graph/d2 cards, --stdin,
tool resolution) added widget + wiring code that dipped total coverage under
the 95% floor — surfaced by `make release` (push-check skips coverage). Cover
the gaps: ProblemsController.refresh, every SVG shape-type bbox + the style
vocabulary, _spawnD2 via a real /bin/cat, the icon-show bus path + error
branches, and quad/arc/close marker paths.

The C client slurps stdin when it sees --stdin, strips the flag, and ships
the payload alongside the argv; the Dart unwrap folds it into the request
as a `stdin` arg (undeclared keys pass the schema untouched). icon.show and
image.show now read that payload as the peer of --file (stdin wins). Bounded
slurp + the envelope's existing size guard keep a huge payload from
corrupting the wire. C client builds clean.

icon.show resolves Phosphor glyphs by name (injected resolver) or a 0xNNNN
codepoint, reads a --file JSON array of {icon,label,description,color}
entries, validates colors via parseSvgColor (hex or CSS name), and
publishes on the `icon` bus channel. Honest userError on an unknown glyph,
a bad color, or a malformed payload. A trailing stringList positional is
now variadic so `icon show gear folder gauge` collects every token.
Flutter-free, dart-tested. Card widget + wiring next.
