Latitude CLI v5.0.0

Changed

• Version realigned to 5.0.0 (from 0.4.0), a deliberate jump with no functional change. A retired, unrelated 2025 CLI published cli-* GitHub releases up to cli-4.0.0 under this same name; those tags carry no platform binaries. Leaping past them makes this crate the unambiguous newest cli-* release by semver, so agents and release-discovery tooling that pick the highest/newest tag resolve to a real, asset-bearing release. Only cli-5.0.0 and later are the real Latitude CLI; cli-4.0.0 and below must be ignored.
