      // ── Turbopack / Next.js 16 module-hash patch (#394, #396, #398) ────────
      //
      // Next.js 16 (with or without Turbopack) compiles the instrumentation hook
      // into a separate chunk and emits hashed require() calls such as:
      //   require('better-sqlite3-90e2652d1716b047')
      //   require('zod-dcb22c6336e0bc69')
      //   require('pino-28069d5257187539')
      //
      // These hashed names don't exist in node_modules and cause a 500 at
      // startup on all npm global installs (issues #394, #396, #398).
      //
      // We use two strategies:
      //  1. Exact-name externals for all known server-side packages.
      //  2. Hash-strip catch-all: any require('<name>-<16hexchars>[/subpath]')
      //     strips the hash suffix and falls through to the real package name.
      //
      const HASH_PATTERN = /^(.+)-[0-9a-f]{16}(\/.*)?$/;
