chore: update .gitignore and improve coding standards documentation

- Added .cursor/sessions/* to .gitignore to prevent session files from being tracked.
- Enhanced coding standards in SKILL.md by adding semicolons to TypeScript examples for consistency.
- Improved formatting in continuous learning, detail layout, and other SKILL.md files for better readability.

These changes aim to streamline development processes and maintain code quality across the project.
