Explain Mermaid rendering fallbacks in the TUI ( #47572 ) ...
## Why
Mermaid diagrams that cannot be rendered currently fall back to source without
explaining why the preview is unavailable.
## What changed
Show a dimmed notice above the preserved source when a completed Mermaid block
uses unsupported syntax, exceeds renderer size limits, or does not fit the
terminal width. Wrap the notice to the available width and preserve indentation
inside lists and blockquotes. Leave unfinished fences and disabled Mermaid
rendering without notices.
## Testing
Add coverage for fallback reasons, dimmed styling, source preservation, nested
indentation, and suppression of notices for unfinished fences and disabled
rendering. Update the streaming resize snapshot to include the width notice.
