What's new

PlantUML diagram rendering

Fenced ```plantuml blocks are now rendered as live SVG diagrams in the preview pane, alongside the existing Mermaid support. The diagram is fetched from the plantuml.com SVG endpoint. If the request fails or the syntax is invalid, the original code block is left in place.

```plantuml
@startuml
Alice -> Bob : Hello
Bob --> Alice : Hi!
@enduml
` ` `

Changes

Added plantuml-encoder dependency and type declaration (src/lib/plantuml-encoder.d.ts) — encodes PlantUML source to the URL format expected by plantuml.com
Added renderPlantUmlBlock private helper in diagrams.ts — fetches SVG from plantuml.com, replaces the <pre> on success, throws on non-ok response (caught silently by renderDiagrams)
Extracted renderMermaidBlocks from renderDiagrams — reduces cyclomatic complexity to satisfy fallow's threshold
Removed unused @highlightjs/cdn-assets dependency
Refactored diagram_rendering.feature from 3 individual Mermaid scenarios to 3 Scenario Outlines covering both Mermaid and PlantUML

Quality

BDD: PlantUML render success, render via preview pipeline, and invalid-syntax fallback all covered by the new Scenario Outlines
Stryker: 100.00% mutation score — 0 survivors; 1 StringLiteral suppressed (error message always swallowed by caller, not observable through public API)
fallow: 0 unused deps · 0 complexity violations · 0 duplication
