GTM API / Delete antidetect browser

Decommission (soft-delete) a single antidetect browser by sid: outward, destructive, one-way through MCP. A browser in an active-run status is stopped FIRST and the node must confirm: the call can take up to ~20s waiting for that confirm, and if it does not arrive the delete is refused with 409 conflict (context.reason=browser_stop_unconfirmed) and NOTHING is deleted - retry in a minute rather than assuming success. Variant B cascade: the bound linkedin-account is soft-deleted and pending plugin tasks transition to failed; the cascade block reports the counts. A platform-minted GoLogin profile is reclaimed (deleted) at the vendor unless another live browser row still holds it; customer BYO and adopted vendor profiles (bound by id) are left intact. Contract: - MCP tool delete_antidetect_browser, registry package mcp.linkedin/antidetect_browsers, mount linkedin.browsers. - Operation delete, response envelope delete_cascade. - Flags: dangerous: the MCP layer gates it behind a preview/commit token, and the effect cannot be undone through this API.
