<#
.SYNOPSIS
    Create a Gitea repository (idempotent).

.DESCRIPTION
    Mirrors deploy_skill/scripts/New-GitHubRepo.ps1. If the repo already exists,
    prints its URL and returns the existing object instead of failing.

.PARAMETER Name
    Repository name (required).

.PARAMETER Description
    Short description.

.PARAMETER Private
    Switch. If set, creates a private repo. Default public.

.PARAMETER Owner
    Optional. User (default) or org to create under.

.PARAMETER NoAutoInit
    Skip the Gitea-side README init (use when you will push an existing local
    repo with its own history).

.EXAMPLE
    .\New-GiteaRepo.ps1 -Name my-app -Description "demo" -Private
    .\New-GiteaRepo.ps1 -Name my-app -NoAutoInit
