The update check ran at most once a day and only printed a line after the TUI exited. Now the registry is asked on every start (in the background, 3 s timeout, no cache) and the result reaches the TUI as a message. With a newer release, the footer shows `q quit and update to vX` right of help and quit, on a highlighted background (Theme.Highlight). `q` quits and `main` installs the release once the terminal is restored, sharing the code of `submarine update`; plain quit moves to `Q`, ctrl+c never updates. Drop LatestCached and CheckInterval. Add D27 and F58. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
