fix(cli): replace update-notifier with simple-update-notifier

[mishushakov]

Summary

Replaced update-notifier v6 with simple-update-notifier v2 to fix the bundled CLI.

update-notifier v6 is ESM-only and spawns a child process (check.js) using import.meta.url. When tsup bundles the CLI into a single CJS file, these file paths become invalid and the update check silently fails. simple-update-notifier is CJS-compatible, checks inline without spawning, and has an identical API surface.

Test plan

• ✓ All 79 existing CLI tests pass
• ✓ TypeScript, linting, and formatting checks pass
• ✓ Update check banner still displays with same interval

Note

Low Risk
Low risk dependency swap and small CLI entrypoint flow change; main potential impact is CLI startup behavior if the new notifier or async sequencing behaves differently across environments.

Overview
Fixes the CLI update banner by replacing update-notifier with simple-update-notifier and removing the old notifier/type dependencies.

Updates the CLI entrypoint to run the update check as an awaited async task (with failures swallowed to avoid unhandled rejections) and switches command parsing to parseAsync() before awaiting the notifier.
