Module display 

2026-09-28: met circuit display: the human view of one fusion plan. It builds a styled document (lines of spans, each span a semantic Style) from the same circuit and plan met circuit show prints; the CLI maps styles to colours.

Owner: metrale-circuit. Invariants:

• Pure: no environment, no TTY probe, no ANSI. Width and glyph set are inputs.
• No line is wider than DisplayOpts::width; below COMPACT_BELOW columns the layout drops the side annotation column instead of wrapping boxes.
• A materialised edge is never drawn inside a fused frame: inside a frame every hand-off is on-chip, and what the kernel also writes is named on the frame’s bottom edge.
