feat: add Solana token analysis example using OpenGradient LLM inference

[Vt01nft]

Summary

Adds a Solana token analysis example using OpenGradient's verifiable LLM inference.

What this example does

• Fetches live Solana token data from DexScreener (price, volume, liquidity, buy/sell txns)
• Sends data to an LLM running on OpenGradient's decentralized network
• Returns a risk assessment with an onchain TX hash as cryptographic proof of execution

Files added

• examples/solana_token_analysis/main.py - core logic
• examples/solana_token_analysis/requirements.txt - dependencies
• examples/solana_token_analysis/README.md - setup and usage guide

How to run

cd examples/solana_token_analysis
pip install -r requirements.txt
export OG_PRIVATE_KEY="0x..."
python main.py

Tested on

• Python 3.12
• opengradient v0.7.4
• Ubuntu 24.04 (WSL2)
