Feature/Issue Description

Q: Please give a brief summary of your feature/fix
A: Added SimpleCov for measuring test coverage across the BeEF codebase. This provides visibility into which parts of the codebase are covered by tests and helps identify areas that need additional testing.

Q: Give a technical rundown of what you have changed (if applicable)
A:
(1) Added simplecov gem (~> 0.22) to the Gemfile
(2) Configured SimpleCov with:

• Filter to exclude spec files from coverage metrics
• Organized coverage groups: Core, Extensions, and Modules
• File tracking for {core,extensions,modules}/**/*.rb

Test Cases

Q: Describe your test cases, what you have covered and if there are any use cases that still need addressing.
A: This change adds test infrastructure rather than testable code. Verified that:

• SimpleCov initializes correctly before application code loads
• Coverage reports are generated after running the test suite
• Files are properly grouped by component (Core, Extensions, Modules)
