ci: setup CI/CD (closes #3)

[sinedied]

Purpose

• Fix lint issues
• Add CI/CD workflows for compliance, build/test and deploy
• Add stale bot for GH issues

Note for @glaucia86 it seems you had an issue with the pre-commit hooks, as the auto-formatting and linting did not work on your last PRs, hence some of the changes in this PR. You should redo an npm install on your side to repair the commit hooks.
