.SYNOPSIS
    Brings up the Musify development environment.

.DESCRIPTION
    Starts the infrastructure stack, generates the stream-ticket keys, applies EF
    Core migrations and provisions Zitadel (project + OIDC app + ClientId).

.EXAMPLE
    ./up.ps1                    # Bring everything up
    ./up.ps1 -SkipMigrations    # Skip the database migration step
    ./up.ps1 -Down              # Stop and remove containers (keep volumes)
    ./up.ps1 -Destroy           # Stop and remove containers + volumes (wipe data)
