Agent Skills: lisa-wiki-tear-down-automations

Remove the recurring LLM Wiki ingest automation that /lisa-wiki:setup-automations created for this project (the lisa-wiki-auto-<project>-* set) using the CURRENT runtime's native scheduler — Codex automations or, on Claude, /schedule. This skill is a declarative specification: it identifies WHICH automation to remove; it does not run teardown scripts. Removes only this project's wiki automations — never the base /setup-automations set, other projects' automations, or non-Lisa ones. The inverse of /lisa-wiki:setup-automations.
