Handle glyph element type in plugin output

[nathanacurtis]

Problem

Glyph elements (icons matched by name pattern) are detected in the data model but the plugin canvas output does not handle them specially. Glyph elements should be rendered with their glyph-specific attributes (e.g., fill color) in anatomy and props sections.

Solution

Add glyph element type handling to the canvas output layer so glyph-specific style attributes render correctly.

Acceptance criteria

• Glyph element type is handled in the canvas output
• Glyph-specific attributes (e.g., fill color) render correctly
