Returns:
    JSON string with all supported chain information.

Implementation Reference

• padex.py:650-676 (handler)

  The main handler function for the 'list_supported_chains' tool. It iterates over CHAIN_CONFIGS to build and return a JSON dictionary of supported chain configurations including RPC URLs, explorers, and contract availability flags.
