Remove unused workflows and update markdown files

Deleted 'link-check' and 'spell-check' jobs from the quality-assurance.yml workflow as they are no longer needed. Updated formatting and structure in multiple markdown files to improve readability and consistency, including financial-analyzer.md, bug-hunter.md, lesson-plan-generator.md, quiz-generator.md, examples/README.md, development-code-review-example.md, and technical-documentation.md.
