Retrieves environment variables, prioritizing those defined in {project_root}/.env.

• Ignores single-line comments (using #)
• Handles empty lines gracefully
• Preserves double-quotes and newline characters in env values

Aims to have rules-parity with dotenv written for node.js.

(require '[dotty.core :refer [env]])

(env "PATH")
;=> "/bin:/usr/bin:/usr/local/bin"

Given your project's .env file contains:

MY_SECRET_KEY=foo1234

Retrieve it with the following:

(env "MY_SECRET_KEY")
;=> "foo1234"
