chore(ci): build, test, release + installer ready

[heronimus]

Closes: DEVOP-73

What is the purpose of the change

• Init CI workflow for build, test (+coverage), and binary release
  • test: execute go test .. + upload coverage results to Codecov.io
  • build: execute go build ..
  • release: upon Github Release event is created, trigger the test, build, and attach the build binary to Github Release.
• Released binary can be installed from our self-hosted installer: curl https://install.world.dev/cli! | bash
• **Skip the current failed unit test for this CI run, need to address this on separate PR.

Testing and Verifying

• Make sure the test, build, and release workflow runs successfully.
• Create a Github Release, wait for release CI to run, and check if all cross-platform binary is uploaded to the corresponding release.

• On your local device, run curl https://install.world.dev/cli! | bash, see if the binary is installed.
