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.

 committed instructions, the API call, and the permission scope are the durable workflow around it.
 Many forges and AI tools ship this as a turnkey app or bot you install and point at a repo; you can
 also build it yourself as a small CI job, or drive it from an editor-integrated agent (Module 4) or
 through MCP (Module 20).
