chore: scaffold, CI, and the export bundle verbatim

The export bundle is the input to this port, not a sketch: the curriculum,
the tutor prompt and the five logic modules are finished and tested. They
land here byte-identical and stay that way.

  diff -r export/data data && diff -r export/lib lib
  diff -r export/prompt prompt && diff export/validate.mjs validate.mjs

data/, lib/, prompt/ and validate.mjs sit at the repo root so validate.mjs
runs verbatim with no path edits. All four are excluded from lint and
formatting — they are not ours to restyle. Types for lib/ live alongside in
types/ rather than as sibling .d.ts files, so the verbatim check stays a
plain directory diff.

CI runs the curriculum gate first, before anything else can pass:

  node validate.mjs   PASS — 0 blocking, 0 advisory
