Bump VERSION + frontend/package.json to 0.43.0, add the CHANGELOG entry
(minor, non-breaking — additive endpoints + UI, no migration, no change to
existing authz outcomes), and mark Part E slice S4 shipped in the design doc.
Completes @S4 (C2.1–C2.7 invitation + C3.3–C3.5 role-aware empty states).
Next: S5 (in-app create-project + the global directory, C3.1–C3.2).
