core: prepare for @ts-check opt-in (app.js + highway.js)

Update the loop_api.test.js regex to tolerate JSDoc cast prefixes on
the slopsmith Object.assign line (needed when files opt into @ts-check
with \`/** @type */ (\\) casts). Adjust slopsmith.d.ts to remove
psarc from the format union (feedback repo is sloppak/loose-only).

The full JSDoc annotations for static/app.js and static/highway.js from
slopsmith/slopsmith#293 require adaptation to the feedback repo's
diverged codebase (v3 UI, capability pipelines, etc.). Files do not
carry \`// @ts-check\` yet, so typecheck passes trivially; the
annotations will be added incrementally in follow-up PRs.
