//! Ubuntu release upgrade action.
//!
//! `UbuntuReleaseUpgrade` triggers a full distribution upgrade via
//! `do-release-upgrade`. This is a Tier 3 action — it is gated behind
//! `RiskLevel::High` and always requires explicit human approval before
//! the daemon will execute it.
//!
//! ## Timeout
//!
//! A full Ubuntu release upgrade typically takes 20–45 minutes. Callers
//! SHOULD configure a long execution timeout (≥ 3 600 seconds / 1 hour) —
//! this is advisory; the daemon does not enforce a minimum. Short timeouts
//! may abort the upgrade mid-flight and leave the system in a partially-
//! upgraded state. Inform the user a reboot is required afterward.
//!
//! ## Risk
//!
//! - Upgrades to the next LTS or interim release.
//! - Non-interactive (`DistUpgradeViewNonInteractive`) but may still fail if
//!   third-party PPAs or pinned packages block the upgrade resolver.
//! - A reboot is required after the operation completes.
