PR Summary

Low Risk
Documentation-only addition of a generated release markdown page; no application or build logic changes.

Overview
Adds apps/site/pages/en/blog/release/v24.18.0.md, a new English release announcement for Node.js 24.18.0 'Krypton' (LTS) dated 2026-06-23, using the standard blog-post front matter (category: release, author Richard Lau).

The post mirrors other release pages: a Notable Changes section (highlights such as NSS root cert update, HTTP agent idle-socket fix, semver-minor buffer/crypto/http/inspector items, and a stream behavior revert), a full Commits changelog with links to upstream PRs, download URLs for all platforms, and a PGP-signed SHASUMS block for v24.18.0 artifacts.
