If crypto/rand fails, the error is printed and the loop continues, which could lead to an infinite loop if the error persists. Consider adding a fallback mechanism or fail-fast after a certain number of consecutive errors.

Pull Request Overview
This PR enhances the project’s build and CI setup while hardening the random track selector in cmd/main.go.
- Switches from
math/randtocrypto/randfor selecting random tracks. - Adds a
Makefileand updatesREADME.mdwith unified build/test/lint commands. - Introduces a GitHub Actions workflow (
.github/workflows/lint.yml) and a.golangci.ymlconfig for automated linting.

Imports are currently unsorted; please group standard library imports together and alphabetize them (e.g., crypto/rand, fmt, math/big, os, os/exec, runtime, strings), then separate third-party imports with a blank line.

Using continue when rand.Int fails can cause an infinite loop if errors persist; consider exiting the program (os.Exit(1)) or returning the error to avoid hanging.

There's a trailing whitespace after US; removing it will keep the file clean and prevent potential lint warnings.

- [nitpick] Consider renaming the variable 'n' to something more descriptive like 'randNum' to improve clarity in the randomness logic.
n, err := rand.Int(rand.Reader, big.NewInt(int64(len(tracks))))
