This pull request introduces a new quality scoring system for nodes and greatly improves the clarity and usefulness of node and pin descriptions across the AI Generative catalog. The most important changes are the addition of a NodeScores object to each node, expanded and clarified descriptions for both nodes and pins, and documentation updates to guide developers on these improvements.

Node scoring system and documentation:

• Added a NodeScores object to every node, providing ratings for privacy, security, performance, governance, reliability, and cost (scale 0–10), visible in the UI for quick assessment of trade-offs. [1] [2] [3] [4] [5] [6] [7]
• Updated developer documentation to recommend clear node/pin descriptions and explain the new scoring system, including auto-generation of pin descriptions when omitted. [1] [2]

Node and pin description improvements:

• Expanded and clarified node descriptions to better explain their function and trade-offs, e.g., for SimpleAgentNode, ChunkText, EmbedDocumentNode, and others. [1] [2] [3] [4] [5] [6]
• Improved pin descriptions for all input and output pins, making their roles and expected data much more explicit. This includes details like execution triggers, model bits, history context, chunking parameters, and output semantics. [1] [2] [3] [4] [5] [6]

Codebase updates for scoring and descriptions:

• Updated imports and usage to include NodeScores in all relevant node files, ensuring consistency and future extensibility. [1] [2] [3] [4] [5] [6] [7] [8]

These changes improve both the developer and user experience by making nodes more self-describing and transparent about their quality attributes.
