ci: add Jenkinsfile and shell.nix for builds

This PR consists of two components:

* `ci/Jenkinsfile.build` - CI build for both Linux, MacOS, and Windows
* `ci/Jenkinsfile.release` - Meta-build that combines two above.

The purpose of the `release` job is to create a single GitHub releas
that combines artifacts from all build jobs.

The GitHub release created is in Draft mode and needs to be edited
to update description and published.

 To create certificates you should first fill in the form, specifying lot number, the quantity of cards for which you need to create a certificate, destination path for the certificates file and choose the output encryption PGP key. You also need a Keycard to sign the certificates. Path `m/43'/60'/1581'/2'/0` will be used to sign.
 
+# Continuous Integration
 
+The CI builds can be found in Jenkins under [keycard-certify](https://ci.infra.status.im/job/keycard-certify/).
+
+The [`release`](https://ci.infra.status.im/job/keycard-certify/job/release/)` job builds the app for Linux, MacOS, and Windows, then publishes all artifacts to a GitHub release based on version set in `package.json`.
