Knowledge bases

Update tag

Rename a tag or change its slot-compatible `fieldType`. Renaming changes read and filter names without moving the slot or its values. Slots are fixed for a tag's lifetime; an incompatible type returns `400` and requires creating a new tag. A duplicate display name returns `409`. Workspace API keys return `403`; use a personal API key or scoped OAuth token. OAuth scope: `api:write`.
