Implement Multi-Coin Market Data Route for CoinGecko Mock API

Description

Task

Create a new route for fetching market data for multiple cryptocurrencies

Acceptance Criteria

• Endpoint accepts a list of coin IDs
• Returns market data for each valid coin ID
• Handles partial success (some valid, some invalid coin IDs)
• Implements input validation
• Provides meaningful error messages
• Supports caching to improve performance
• Matches CoinGecko API response structure

Summary of Work

This pull request adds a new endpoint to the CoinGecko mock API for retrieving market data for multiple cryptocurrencies. The implementation will support fetching market information for a list of specified coin IDs, enhancing the API's flexibility and usability.

Changes Made

• Create new route handler in src/routes/market-data.ts
• Add input validation for coin ID list
• Implement data retrieval logic for multiple coins
• Create mock data generation utility for market data
• Add error handling for invalid coin IDs
• Implement caching mechanism for market data responses

Tests

• Verify route returns correct data for valid coin IDs
• Test error handling for empty coin ID list
• Validate response structure matches expected format
• Check caching functionality for repeated requests
• Test performance with multiple coin ID queries
• Validate input validation for coin ID formats
