Add CI workflows, spellcheck, and update configs

Added GitHub Actions workflows for spellchecking and linting, configured Dependabot for dependency updates, and introduced .cspell.json and .gitattributes for consistent spelling and line endings. Updated .htmlhintrc with additional HTML validation rules, improved the email pattern in README.md, and made minor changes to index.html and package.json.
