* Add missing fast-boot `stop()` call on CLI exit to avoid 1s timeout.
* Move `.fast-boot.json` to `~/.balena/cli-module-cache.json` to
address scenarios where the CLI is installed to a read-only folder:
- pkg's internal 'snapshot' filesystem (standalone zip package)
- Root-owned folder without write permission to regular users,
like `/usr[/local]/lib/balena-cli` (the case of caxa-based
installers or the GUI installer for macOS).
