One binary: the lint and the trainer are commands of portal

portal serve runs a site; portal lint is what iris was; portal plan,
build, report and the rest are what portal-trainer was. One source at
one version, so the three never disagree about what content means.
Both histories are merged in (subtree). The release attaches the bare
binary for a content repo's CI. The trainer's plans, intakes, engines
and reference prompt come along; its runs stay in the old repo.

+//! Makes a simulation's cases real: every case becomes an aggregate in
+//! its bucket, created and moved by the same code the running site
+//! uses - `answers::store_answer` for the submission,
+//! `aggregates::transition` for each desk move, against a real
+//! JetStream with its event log and its refusal of undeclared moves.
+//! Then the buckets are read back by replaying each record's events,
+//! and reported per need against `done_when` and `success`.
+//!
+//! The report half runs on its own (`--report-only`) against any
+//! JetStream, which is how the same scorecard is taken from a live
+//! site's buckets.
+//!
+//! Point it at a throwaway NATS, never a site's own: it writes.
