[yuiseki]

Description

This pull request introduces several improvements to the project's configuration, documentation, and development workflow. The most important changes include updates to documentation for platform-specific build guides, enhancements to development environment settings, and the addition of configuration files for ignoring build artifacts and specifying tool versions.

Documentation updates:

• Updated the README.md to point to new locations for platform-specific build guides and replaced the Windows build guide link with the correct filename.
• Updated the Windows build instructions to use parallel builds with the -j flag for faster compilation.

Development environment improvements:

• Added file associations for __tree and map as C++ files in .vscode/settings.json to improve editor support.

Configuration and tooling:

• Added .clang-format-ignore to exclude build/*, build-ninja/*, and vendor/* from formatting checks.
• Added rust stable to .tool-versions to specify Rust as a required tool for the project.
