This commit fixes a critical build issue where the application was being compiled as an archive instead of an executable. This was caused by the absence of a `main` package.
The following changes have been made to resolve this and improve the development process:
- A `main.go` file has been added to the root of the project to serve as the application's entry point.
- A `Taskfile.yml` has been introduced to standardize the build, run, and testing processes.
- The build process has been corrected to produce a runnable binary.
- An end-to-end test (`TestE2E`) has been added to the test suite. This test builds the application and runs it with the `--help` flag to ensure the binary is always executable, preventing similar build regressions in the future.
