Pull request overview

This PR introduces an off-chain tool for prepopulating locked token data as part of a contract migration process. The tool queries token total supply across multiple blockchain networks (NEAR, Ethereum, Arbitrum, Base, BNB, Polygon, and Solana) and generates JSON output files containing locked token amounts per chain.

Changes:

• Added a new Rust CLI tool (prepopulate-locked-tokens) that fetches token supply data from multiple chains
• Created token list files for testnet and mainnet with native, NEP141, and factory-deployed tokens
• Generated pre-computed JSON output files with locked token amounts for each chain
