docs: point terminal users at codeman tui instead of the sc chooser

codeman tui supersedes the sc bash chooser: it reaches sessions 10+,
carries the server's real states instead of a static list, and leaves an
attach with one key. Every place that told a user to run sc now names the
tui equivalent, including the two wiki pages and install.sh's next-steps
banner. Both wiki pages also carried the wrong detach chord (Ctrl+A D;
the socket's prefix is C-b), which the tui makes moot.

Source comments that explained themselves as "the sc -l replacement" now
just say what they do. docs/tui-plan.md and CHANGELOG.md are historical
records and keep their references.

+You do not have to use a browser. `codeman tui` is a full-screen session dashboard that
+works well in SSH clients like Termius or Blink:
 
 ```bash
-sc          # interactive chooser
-sc 2        # attach to session 2
-sc -l       # list
+codeman tui           # the dashboard
+codeman tui 2         # attach straight to session 2
+codeman tui --list    # numbered list, then exit
 ```
 
-Detach with `Ctrl+A D`. The sessions are the same ones the dashboard shows.
+`Enter` attaches into the pane and `F1` comes back. Under 72 columns it drops the preview
+and becomes a single-column list, so it stays usable on a phone. The sessions are the same
+ones the dashboard shows. See [docs/tui.md](https://github.com/Ark0N/Codeman/blob/master/docs/tui.md)
+for the full guide.
