"""End-to-end test of the hello reference plugin (SPEC §11, §12 M3 acceptance).
Exercises the whole vertical against the real HTTP surface: entry-point discovery
-> router mounted at /api/plugins/hello -> SDK auth (CurrentUserId) -> RLS-scoped
session -> the plg_hello_note table. Also proves per-user isolation: one user never
sees another's notes. Requires the plugin installed + `install hello` run.
