feat: Semantic Model Dependency Extension for Standards Graph

[Copilot]

• Explore codebase and understand existing state
• Create SemanticModelNode.js — diamond-shaped React Flow custom node
• Add diamond CSS to StandardsGraph.module.css
• Update StandardsGraph.js — SM nodes/edges, two-ring layout, focus analysis, MiniMap
• Update GraphControls.js — "Show Semantic Models" toggle + legend diamond
• Update NodeInfoPanel.js — SM node detail panel when a model node is clicked
• Fix build error: duplicate declarations in NodeInfoPanel.js
• Create kitEnricher.js — script to fetch KIT→CX-standard cross-refs from eclipse-tractusx repo
• Update all 4 static JSON files with kitIndex sample data + referencedByKits per node
• Create KitNode.js — hexagonal React Flow custom node for KITs
• Add hexagon CSS to StandardsGraph.module.css
• Update StandardsGraph.js — KIT nodes/edges, multi-ring layout, focus analysis
• Update GraphControls.js — "Show KITs" toggle + legend hexagon
• Update NodeInfoPanel.js — KIT node detail panel + "Referenced by KITs" on standard nodes
• Address code review: remove /g flag from CX_REGEX constant, extract RING_SPACING constant, introduce KIT_COLOR constant in GraphControls.js, add hexagon geometry comment to CSS

@copilot verify website build and deploy th gh pages doesnt work. It seems the npm run build results in an error

Fixed in commit 70820cc. The build failure was caused by duplicate function declarations in NodeInfoPanel.js — when the file was rewritten the old code block (352 lines including duplicate SemanticModelStatusBadge, SemanticModelsSection, CategoryPillar, CATEGORY_CONFIG, and the NodeInfoPanel default export) was left trailing after the new code, triggering a Babel SyntaxError: Identifier 'SemanticModelStatusBadge' has already been declared. The stale duplicate block has been removed.
