/**
 * Build a self-contained .mcpb bundle for pdf-server.
 *
 * `mcpb pack` zips whatever is on disk; in this monorepo all runtime deps
 * are hoisted to the root node_modules, so packing in-place produces a
 * bundle with no pdfjs-dist/ajv/etc. that crashes in Claude Desktop.
 *
 * This script stages dist/ + manifest into a clean temp dir, runs a fresh
 * non-workspace `npm install --omit=dev --omit=optional` (the polyfill in
 * dist/pdfjs-polyfill.js makes @napi-rs/canvas's ~130MB of native binaries
 * unnecessary), syncs the manifest version to package.json, then packs.
