<#
.SYNOPSIS
    Create a new GitHub repository for a project that will be deployed to Coolify.

.DESCRIPTION
    Calls the GitHub REST API with GITHUB_TOKEN to create a new repository under
    the authenticated user. After creation, prints the clone URL (HTTPS) and the
    SSH push URL. Idempotent in the sense that if the repo already exists it
    aborts with a clear message instead of failing.

.PARAMETER Name
    Repository name (required). GitHub naming rules: lowercase, digits, '-' '_' '.'.

.PARAMETER Description
    Short description shown on GitHub.

.PARAMETER Private
    Switch. If set, creates a private repository. Default is public (Coolify
    public-app deploy does not need a deploy key).

.PARAMETER Owner
    Optional. Organization or user to create the repo under. Defaults to the
    authenticated user (the owner of GITHUB_TOKEN).

.EXAMPLE
    .\New-GitHubRepo.ps1 -Name "my-cool-app" -Description "Demo" -Private
