Overview
This PR introduces a set of well‑crafted prompt templates designed to help Ender generate accurate and useful outputs for a variety of blockchain use‑cases. The templates cover the most frequent application types developers encounter, reducing trial‑and‑error and improving productivity.

File	Purpose
docs/prompt_templates/defi_dashboard.md	Prompt template for creating DeFi dashboard interfaces, covering key metrics, data sources, and UI components.
docs/prompt_templates/nft_marketplace.md	Prompt template for NFT marketplace generation, including collection metadata, minting flow, and marketplace features.
docs/prompt_templates/dao_governance.md	Prompt template for DAO governance platforms, covering proposal structures, voting mechanisms, and token‑based voting logic.
docs/prompt_templates/payment_application.md	Prompt template for blockchain‑based payment applications, detailing payment flows, integration points, and security considerations.

Why This Matters
Consistency – Provides a standardized way to ask Ender for blockchain‑specific content.
Efficiency – Cuts down on repetitive prompt crafting, letting developers focus on core logic.
Quality – Embeds best‑practice guidance (e.g., security notes, gas‑optimisation hints) directly into the prompts.
