claude 389ac2e460 style(no-slop): remove every em-dash + banned words across all modules + capstone
Apply the no-ai-slop standard (now binding in AGENTS.md): the em-dash character is
banned outright (restructured, not blind-replaced), plus the banned word/phrase
list (delve, leverage, robust, seamless, truly, unlock, etc.). 0 em-dashes remain
in modules + capstone; the only "robust" left is the planted M10 ai-change.patch
trap. Module H1 titles use a colon separator.

All deliberate teaching devices preserved; labs compile/parse (py/sh/yaml/json);
no junk. AGENTS.md updated with the hard no-slop rules.

"""Tiny command-line front end for the demo task app.
Run it:
python cli.py add "write the lesson"
python cli.py list
python cli.py done 0
State is kept in tasks.json next to this file. The `done` command turns a bad index into a
clean error message and a non-zero exit code; note that behavior before you review the AI
change, so you can tell if the change quietly alters it.
