/**
 * Honest typecheck. Runs `tsc --noEmit` over the whole project (client + server;
 * see tsconfig.json "include": ["src", ...]).
 *
 * A fresh consumer who `bun install`s the PUBLISHED deps gets compiled `.d.ts`
 * (skipped by skipLibCheck) and sees only the project's own errors — nothing to
 * filter. In this repo's local dev, sibling libs are SYMLINKED into node_modules
 * as raw `.ts` source (relink-libs.sh), so tsc follows the import graph into that
 * source and reports errors that no real consumer ever hits. tsc can't be told to
 * skip `.ts` under node_modules (skipLibCheck only skips `.d.ts`), and `exclude`
 * doesn't stop import-following — so we strip exactly those dep-source lines here.
 *
 * This never hides a shraga error: everything that isn't a `node_modules/` or
 * `../sibling` source path is passed through, and the exit code is non-zero if any
 * such line remains. It only removes noise from linked dependency source.
