The target is the signed-in account plus the project coordinates: a team
name, a save domain, and a save group.

Use this when the user asks where their memory is being saved, asks to switch
project, or when expected memory seems missing and the account or project may
have changed. It does not change the target. On a Main-following connection
the switch happens when the user opens `switch_url` and clicks; the `note`
field says how switching works on this connection. On a pinned connection
(`binding` = `folder` or `api-key`) `switch_url` is null: the console
cannot move it, and `switchable_via` says what the user changes instead.

Read-only.

Returns:
    `{team, account, account_email, project, binding, read_only, link_id,
    save_domain, save_group, switch_url, switchable_via,
    multi_connection_note?, persona?, emergency_notice?, note}`. `binding`
    says what the target is pinned to:
    `folder` and `api-key` mean this connection is pinned to that project and
    a console switch elsewhere does not move it (so `switch_url` is null);
    `main` means it follows the account-wide preset and can change
    mid-session; `public-read` and `link-read` are read-only binds where
    saving is disabled. `multi_connection_note` appears only when `binding`
    is `main`: saves belong on a `folder` or `api-key` AiAkiv connection if
    the conversation has one. `persona`, when present, is a project-level
    note set by the project owner in the web console.
