Default the ai mode to qwen2.5-coder:1.5b instead of the hardcoded (and
uninstalled) westenfelder/NL2SH, which left ai mode broken. The model is now
configurable via SUPERMAN_AI_MODEL / --model, with markdown-fence stripping and
a coder-specific prompt wrapper so general coder models emit a single bare
one-liner. NL2SH still receives the raw query. Adds --compare to run multiple
models side by side (SUPERMAN_AI_COMPARE_MODELS) with timing for benchmarking.

Rename bash-helper.sh -> super-man.sh and update all docs/tests to the
super-man name and alias. In interactive mode, pressing Esc in the flag
browser now returns directly to the home menu, removing the intermediary
"Press Enter to search another command" prompt.
