This pull request adds a new article to the documentation, introducing the DIMA browser add-on for online vigilance. The article explains how the DIMA tool works, its purpose, and provides real-world examples of its application. It also clarifies common misunderstandings about the tool's scoring and its approach to identifying disinformation.

New content addition:

• Added a detailed article (DIMA_vigilance.md) presenting the DIMA Firefox add-on, describing its static analysis of web pages for cognitive bias techniques, and outlining the framework's four-phase model for influence operations.
• Included explanations and screenshots to illustrate how the tool scores various sites (including reputable news outlets), and how it flags domains identified in disinformation reports such as CopyCop (Storm 1516).
• Clarified that the tool is designed for user awareness and does not directly detect disinformation, but highlights techniques that may exploit cognitive biases, and provides links to source reports for further investigation.
