Remove ONE table from the company's membership while keeping the account (other memberships, people links, tags, notes, activities intact) - the "remove row from this table" gesture. The detached table's cells are hard-deleted by job - destructive to that table's cell data. Idempotent: a non-member playtable_sid returns result.detached:false, no changes. Detaching the last table is allowed (empty membership). NOT a delete - delete_company removes the account everywhere.

Contract:

• MCP tool detach_company_playtable, registry package mcp.playtables/companies, mount playtables.people.
• Operation action, response envelope action.
• Flags: dangerous: the MCP layer gates it behind a preview/commit token, and the effect cannot be undone through this API.
