feat: fastpool with atomics

[Lojhan]

This pull request removes a significant amount of project configuration and test infrastructure, streamlining the repository and its CI/CD process. The changes eliminate Rust and Yarn configuration files, remove all test files, and greatly simplify the GitHub Actions workflow by dropping multi-platform build and test jobs in favor of a single, simpler Node.js-based test job. The overall effect is a major reduction in project complexity, especially around cross-platform support and Rust build/test infrastructure.

CI/CD Workflow Simplification:

• The .github/workflows/CI.yml file is heavily refactored to remove all cross-platform build and test jobs, including matrix builds for various targets and architectures, FreeBSD and WASI builds, and artifact handling. The new workflow only runs linting, formatting, and Node.js-based tests across a matrix of Node.js versions and operating systems. The publish step is also simplified to a single npm publish command.

Removal of Rust and Yarn Configuration:

• The Rust project configuration files Cargo.toml and .cargo/config.toml are deleted, removing all Rust build settings and dependencies. [1] [2]
• The Yarn configuration file .yarnrc.yml is deleted, removing custom Yarn settings.
• The .prettierignore and .taplo.toml files are removed, eliminating Prettier and Taplo (TOML linter/formatter) ignore and formatting rules. [1] [2]

Test Suite Removal:

• All test files under __test__/cjs/ are deleted, including core, concurrency, and lifecycle tests for the GenericObjectPool. [1] [2] [3]

Editor and Tooling Settings:

• A new .vscode/settings.json is added to auto-approve the use of npx tsx in the VSCode terminal, improving developer experience for TypeScript execution.

Summary of Most Important Changes:

1. CI/CD and Build Process Overhaul

• Major simplification of .github/workflows/CI.yml: removes all multi-platform Rust build and test jobs, artifact handling, and replaces them with a single Node.js-based lint and test workflow. The publish step is also streamlined. [1] [2] [3] [4]

2. Removal of Rust and Yarn Configuration

• Deletes Cargo.toml, .cargo/config.toml, and .yarnrc.yml, removing all Rust and Yarn-specific configuration and dependencies. [1] [2] [3]

3. Test Suite Deletion

• Removes all test files for the GenericObjectPool, eliminating automated test coverage for core, concurrency, and lifecycle features. [1] [2] [3]

4. Project Formatting and Linting Configuration

• Deletes .prettierignore and .taplo.toml, removing Prettier and Taplo ignore and formatting rules. [1] [2]

5. Editor Tooling

• Adds .vscode/settings.json to auto-approve npx tsx in VSCode terminal for smoother TypeScript workflow.
