fix(cli): preload deferred rich/typer modules before in-place upgrade

brew upgrade / uv tool upgrade delete the running install's files while the old process is still alive. rich defers importing rich._emoji_codes until print time and typer defers typer.rich_utils until excepthook time, so printing the post-upgrade status message crashed the exiting process with ModuleNotFoundError (and the traceback renderer crashed too). Import both before launching the upgrade subprocess, while the files still exist.
