fix(setup): drop post-setup chat handoff (#25067)

Removes the 'Launch hermes chat now? (Y/n)' prompt at the end of
hermes setup. The summary already prints 'Ready to go! → hermes'
so the auto-launch was redundant, and on macOS 26+ it could crash
in prompt_toolkit when setup was invoked from the curl install
script with stdin redirected from /dev/tty (#5884, #6128).

After setup, users run 'hermes' themselves like every other CLI
tool. Same pattern applies to the Windows installer.

Closes #6128 (narrower env-var-guarded fix superseded by removing
the prompt outright).
