Say that a model can be typed in, everywhere one can

Every model box has taken a typed name all along, but nothing said so, and a
closed-looking list reads as the whole choice. The Claude Code and Codex boxes
now carry a tooltip saying the list is a starting point, not a fence. Claude
gets no fetched list of its own: its CLI has no catalog command, and the
aliases it takes (sonnet, opus, haiku, fable) already follow the newest model
of each line.

+"""Whether a newer Dikte has been published, and where to get it.
+
+GitHub is asked for the newest release, its number is held against the one this
+build carries, and that is where it stops. Nothing is downloaded and nothing is
+replaced. The four downloads are installed in four different ways, and three of
+those belong to the platform rather than to Dikte: a Mac bundle is dragged into
+Applications and cannot rewrite itself while it is running, the Windows setup
+is an installer with an uninstall entry of its own, an AppImage is a single
+file kept wherever its owner keeps it, and a checkout is updated with git. A
+program that guessed at all four would be wrong on at least one of them, and
+being wrong there means an installation somebody has to repair by hand. So the
+answer ends in a browser, on the release page, where the same download that was
+installed the first time is waiting.
+
+The clock is kept in a file of its own rather than in the settings. A check
+runs while the settings window may be open, and a background write into
+config.json is exactly what would overwrite a setting somebody is in the middle
+of changing.
+
+Nothing here imports Qt or the rest of the application: `dikte update` at a
