This pull request modernizes and streamlines the project by updating dependencies, refactoring wallet integration, and improving CI workflows for both Rust and TypeScript contracts. The most important changes are grouped below.

---

Frontend Modernization and Wallet Integration:

• Migrated from @near-wallet-selector and related packages to near-connect-hooks, simplifying wallet integration and removing EVM wallet support and related configuration. Updated UI to use new wallet hooks and improved sign-in UX by specifying function call access keys. (frontend/package.json, frontend/src/components/Navigation.jsx, frontend/src/pages/_app.js, frontend/src/config.js) [1] [2] [3] [4] [5]
• Upgraded near-api-js and other dependencies to latest versions, and updated React/Next.js to v19/v16 for improved performance and compatibility. (frontend/package.json)
• Updated Node.js engine requirement to v20+. (frontend/package.json)

Continuous Integration Improvements:

• Updated GitHub Actions workflows to use pnpm instead of yarn, Node.js v24, and limited workflow triggers to relevant paths for better efficiency. (.github/workflows/nextjs.yml, .github/workflows/tests-ts.yml, .github/workflows/tests-rs.yml) [1] [2] [3] [4]
• Added concurrency controls to prevent duplicate workflow runs and improved caching and dependency installation steps for Rust and TypeScript contract tests. (.github/workflows/tests-ts.yml, .github/workflows/tests-rs.yml) [1] [2] [3]

Smart Contract and Testing Updates:

• Upgraded Rust toolchain to 1.97.1 and updated near-sdk, cargo-near-build, and tokio dependencies for the Rust contract. Removed temporary dependency version pins. (contract-rs/Cargo.toml, contract-rs/rust-toolchain.toml) [1] [2]
• Refactored TypeScript contract tests to use near-sandbox and near-api-js directly, replacing near-workspaces and modernizing test structure for better maintainability and speed. (contract-ts/sandbox-test/main.ava.js, contract-ts/package.json) [1] [2]
• Updated TypeScript configuration for ES2020, module resolution, and improved test settings. (contract-ts/tsconfig.json, contract-ts/package.json) [1] [2]
