Added a new .markdownlint.json configuration file to manage markdown linting rules. Removed .spellcheck.yml and .wordlist.txt as they are no longer needed. Updated several markdown files to simplify content and remove outdated references.
Introduced `.spellcheck.yml` for configuring spellchecking in Markdown files and added `.wordlist.txt` with custom terms to enhance spellchecking accuracy.
