/**
 * Interactively configures environment variables for a project by prompting the user
 * to provide values for empty variables or variables marked as secrets.
 *
 * This function reads from .env.example and, when the user confirms configuration,
 * copies it to .env before prompting for values. The .env.example file remains
 * unchanged as a template for other developers.
 *
 * @param projectPath - The absolute path to the project directory containing the .env.example file
 * @param skipPrompt - If true, copies .env.example to .env without interactive prompts and returns false
 * @returns A promise that resolves to true if environment variables were successfully configured,
 *          false if configuration was skipped (no .env.example file, user declined, no variables to configure,
 *          or an error occurred)
