Update 1c-rules
Call install.ps1 update through the plugin wrapper. Do not overwrite USER-RULES.md, memory.md, or LLM-RULES.md.
powershell.exe -NoProfile -ExecutionPolicy Bypass -File "<plugin>/scripts/invoke-install.ps1" -Action update -ProjectRoot "<project-root>"
If .ai-rules.json is missing, this is a first install: use the install skill (-Action init), not update.
