Remove bigint-buffer dependency by upgrading @solana/web3.js to 2.0.0

Remove bigint-buffer dependency by upgrading @solana/web3.js to 2.0.0

Summary

This PR removes the bigint-buffer dependency from the worldstore-agent repository by upgrading @solana/web3.js from version 1.x to 2.0.0. The bigint-buffer dependency was only present as a transitive dependency through the chain: @solana/[email protected] → @solana/buffer-layout-utils → bigint-buffer.

The solution uses pnpm overrides to force @solana/web3.js to version 2.0.0, which no longer depends on bigint-buffer as it now uses native BigInt support instead.

Key changes:

• Added pnpm override for @solana/web3.js: "2.0.0" in package.json
• Updated pnpm-lock.yaml with new dependency tree
• Verified bigint-buffer is completely removed from dependency tree
• Build and type checking still pass

Review & Testing Checklist for Human

Risk Level: 🟡 Medium (2 critical items to verify)

• End-to-end functionality verification: Test core application flows that involve Solana operations to ensure the major version upgrade of @solana/web3.js doesn't break existing functionality
• Runtime error checking: Start the application and verify no runtime errors occur during Solana-related operations, especially around BigInt/buffer conversions

Notes

• This is a major version upgrade (1.x → 2.x) of @solana/web3.js, which could introduce breaking API changes
• The upgrade uses pnpm overrides to force dependency versions, which may cause peer dependency warnings (visible in install output)
• No direct code changes were needed since the repository doesn't directly import bigint-buffer or @solana/web3.js APIs
• @solana/[email protected] is marked as deprecated in favor of @solana/kit, but this approach still achieves the goal of removing bigint-buffer

Original prompt from Penelope

Please go to each of the following repositories and see if you can you remove the dependency to bigint-buffer and replace it with an alternative such as BigInt without breaking anything?
