remove emojis and rename RPC environment variable

[moltrus]

Description

Emoji Removal

Replaced all emojis and Unicode characters (like ✅, 📝, 🚀, and →) in log messages and internal labels with standard ASCII characters (true, false, and ->). Because MCP uses the same console (STDOUT) for data, Claude Desktop tries to parse that checkmark as JSON, fails, and stops loading the tools entirely.

Configuration Update: Renamed POLYMARKET_RPC_URL to POLYGON_RPC_URL.

This provides better clarity as the RPC specifically connects to the Polygon network rather than a Polymarket-specific infrastructure.

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request primarily focuses on improving compatibility and clarity within the project. It removes problematic emoji and Unicode characters from log outputs and internal labels to prevent parsing issues with tools like Claude Desktop. Additionally, it renames an environment variable for Polygon RPC to enhance its descriptive accuracy.

Highlights

• Emoji and Unicode Character Removal: Replaced various emojis (e.g., ✅, 📝, 🚀) and Unicode characters (e.g., →) in log messages and internal labels with standard ASCII equivalents (e.g., "true", "false", "->"). This change addresses an issue where Claude Desktop's MCP console would misinterpret these characters as JSON, causing parsing failures and preventing tool loading.
• Environment Variable Renaming: Renamed the POLYMARKET_RPC_URL environment variable to POLYGON_RPC_URL across the codebase and documentation. This provides clearer semantics, indicating that the RPC URL specifically pertains to the Polygon network rather than a Polymarket-specific infrastructure.

Code Review

This pull request removes emojis and Unicode characters from log messages and labels to prevent parsing issues, and renames the POLYMARKET_RPC_URL environment variable to POLYGON_RPC_URL for better clarity. The changes are well-aligned with the description. I've suggested one improvement to maintain backward compatibility for the renamed environment variable, which would make the transition smoother for existing users.

[gemini-code-assist]

To maintain backward compatibility, consider also checking for the old POLYMARKET_RPC_URL environment variable if POLYGON_RPC_URL is not set. This would prevent breaking setups for existing users and make the transition smoother.
