    // The @lastdb/app-sdk is vendored as a committed prebuilt directory under
    // vendor/ rather than installed as a package. A relative `file:` dependency
    // does NOT survive a `bun add github:EdgeVector/fbrain` install — bun extracts
    // the repo tarball but never runs a nested install for fbrain's own file:
    // deps, so no node_modules/@lastdb/app-sdk symlink is created and the bare
    // specifier fails to resolve at runtime. Resolving `@lastdb/app-sdk` via a
    // tsconfig path alias instead removes the install-time dependency entirely:
    // bun honors these paths relative to the ENTRYPOINT's directory (verified for
    // a globally-installed bin run from any cwd), so it resolves whether fbrain is
    // a local clone or installed under node_modules/fbrain/ from a github:
    // specifier. To refresh the SDK, replace vendor/lastdb-app-sdk/ with a freshly
    // unpacked @lastdb/app-sdk tarball (tar xzf … --strip-components=1).
