Require Node.js >= 20.18.1 and bump Undici to 7, restoring proxy and custom‑CA support on recent Node versions.

Full changelog

Patch Changes

  • beded6c: Bump undici to 7 and require Node.js >= 20.18.1. On Node 26+ (internal undici 8) the bundled undici 6 setGlobalDispatcher wrote a global-dispatcher symbol the built-in fetch no longer reads, so HTTPS_PROXY and custom-CA settings were silently ignored and requests failed with ENOTFOUND behind CONNECT proxies. undici 7 writes both symbols, restoring proxy and CA support. Node 18 is no longer supported (EOL; undici 7 requires Node >= 20.18.1).
  • 1c081df: Improve query prompts so agents request relevant library documentation instead of passing the task to complete.

Breaking Changes

  • Minimum Node.js version increased to >=20.18.1 (Node 18 no longer supported).
  • Undici dependency bumped from version 6 to version 7.
