<#
Esporta ogni skill (plugins/*/skills/<nome>/) in uno zip separato in dist/,
pronto per essere caricato come skill singola su Claude (Settings -> Capabilities -> Skills)
per test rapidi senza passare dall'installazione dell'intero plugin/marketplace.

Uso:
  powershell -File scripts/export-skills.ps1
  powershell -File scripts/export-skills.ps1 -Skill o-ring   # esporta solo una skill

Ogni zip contiene i file della skill alla radice dell'archivio (SKILL.md in cima),
non dentro una sottocartella, come richiesto dal caricamento manuale su Claude.
