Summary

Show a small, unobtrusive "new version available" notice shortly after Hunk starts when the installed version is behind the latest published release.

Why

Hunk is a terminal app that people may install once and then keep using for a while. A lightweight startup notice would make it easier to discover updates without requiring users to manually check npm or GitHub.

Suggested behavior

• check occasionally in the background rather than on every launch
• only show when a newer version exists
• keep it subtle and transient (for example a short-lived status/toast-style message)
• avoid blocking startup or taking over focus
• ideally mention whether the newer version is latest or beta
• if/when we add an update command, the notice could point to that flow
