Measuring Go Code Coverage with Bincover

What this post added

Introduces Bincover, an open-source tool for measuring Go binary code coverage. Details the technical approach of instrumenting binaries with a fake test that runs the main function, and how Bincover enhances this by handling command-line arguments, panics, and `os.Exit()` calls. Explains the implementation details of argument parsing via an args file, coverage profile collection using `-test.coverprofile`, and metadata collection for exit codes and cover modes. Provides a practical example of using Bincover with a simple Go application and its test suite.
