/**
 * Update Command
 * Issue #1194: bundle `stop` -> `npm install -g commandmate@latest` -> `start`
 * into a single command for globally installed users.
 *
 * Design constraints (see Issue #1194 決定事項):
 * - All dependencies are imported statically at the top level (S3-011). After
 *   step 7 npm replaces the package directory, so a dynamic import()/require()
 *   at that point would fail with MODULE_NOT_FOUND.
 * - isGlobalInstall / npm execution / daemon operations are reached through
 *   separate modules so tests can seam them with vi.mock (D-9).
 * - startCommand()/stopCommand() are never called: they process.exit() on every
 *   path, which would kill this process mid-update (D-6 / S1-002).
 * - process.exit is only reached at the end of a branch, each followed by
 *   `return;` (tests stub process.exit, so execution continues).
 *
