Emacs Bedrock 2.0

Emacs Bedrock 2.0 has been released, requiring Emacs 31 and featuring a minimal, comment-guided configuration approach with no third-party dependencies in its base setup. The major update includes lexical binding across all files, automatic package installation with use-package, improved tree-sitter support, and incorporation of built-in Emacs features like repeat-mode and grep-change-to-grep-edit-mode. The release prioritizes incremental improvements while maintaining Bedrock's philosophy of users directly managing their own configuration files rather than relying on automatic upgrade mechanisms.
