isb-daemon 1.10.0

//! The account tools: who is calling (`whoami`), an org's members,
//! invitations and tokens, the caller's own API tokens, SSH keys and
//! sessions, and (platform admins) users. The same operations as the
//! identity endpoints under `/api/v1/auth/` ([`crate::auth::ops`]), so MCP
//! and REST callers get the web UI's account pages with the same rules:
//!
//! - A workspace token reaches none of them but `whoami`.
//! - A token scoped short of `admin` only reads them.
//! - A token never mints tokens (`token_create` needs a browser session, an
//!   Access or tailnet identity; the host CLI mints too).
//! - Org rules (members see their org; owners and admins manage it; only an
//!   owner touches an owner) are [`crate::auth::ops`]'s.
//!
//! The control plane runs them itself (the identity store is its own); an
//! agent refuses them.
