0.7.5

Changed

• child_process is required directly again in the Codex/OpenCode CLI provider and the Word
  export. Routing it through the shared nodeRequire helper in 0.7.4 hid it from the Community
  review's static scan, so the review stopped reporting that the plugin runs external programs.
  It does (only when those features are used, and the README says so); the scan should see it.
• Embedding vectors and PDF highlight rectangles are checked with an isNumberArray type guard
  instead of a cast.
