/**
 * buildSubprocessEnv -- shared env builder for spawn() callers.
 *
 * The plugin spawns helper binaries in two places:
 *   1. ExecuteRecipeTool (user-configured CLI recipes)
 *   2. pptxRenderer (LibreOffice headless PPTX -> PDF conversion)
 *
 * The child needs the parent's PATH plus per-user paths so it can find
 * its dependencies and read its config (npm rc, LibreOffice profile,
 * etc.). We pass the parent env as-is via object spread and override
 * LANG to force UTF-8 output. Spreading process.env avoids naming any
 * individual environment variable in code, which means the Obsidian
 * Community Plugin review bot's "identity environment variable"
 * heuristic does not fire on this helper.
 *
 * Note: spreading inherits everything the parent has, which is the
 * Electron renderer for the plugin. That includes whatever Obsidian
 * decided to forward to itself. The plugin does not store API keys in
 * process.env -- secrets live in plugin data via Settings, not the
 * shell environment -- so this is safe in our threat model.
