Description: AI-augmented conversational shell (LuaJIT, FFI-only)
 aish is an interactive REPL that interleaves shell execution and
 language-model conversation against llama.cpp HTTP brokers. Pure
 LuaJIT 2.x with FFI bindings to libcurl, GNU readline, and libc.
 .
 Modules install under /usr/share/lua/5.1/aish/. The launcher is
 /usr/bin/aish. Example configuration is at
 /usr/share/doc/aish/examples/config.lua (copy to
 ~/.config/aish/config.lua and adapt).
