# ── VibeFinance release script (PowerShell) ──────────────────────────────
# Productie release: bouwt multi-platform, pusht naar registry,
# maakt een Git-tag aan en pusht naar origin.
#
# Gebruik:
#   .\release.ps1              # bouw + push images + Git-tag
#   .\release.ps1 -NoBuild     # sla docker build over, alleen Git-tag
#   .\release.ps1 -DryRun      # toon alle commando's zonder iets uit te voeren
#   .\release.ps1 -Force       # sla conflictcontrole over, overschrijf bestaande tags
#
# Vereisten:
#   - Docker Desktop actief
#   - Ingelogd op de registry: docker login <registry>
#   - docker buildx builder actief: docker buildx create --use
#   - Git geïnstalleerd en working directory is de repo root
#   - root package.json bevat een schoon versienummer ZONDER -dev suffix
