domain-modeling: drop the "another skill needs to maintain" caveat

Every skill that delegates to domain-modeling (grill-with-docs,
wayfinder, improve-codebase-architecture, triage) already invokes
/domain-modeling explicitly by name, so the description never needed
to carry that branch — it's the invoking skill's job to say so, not
this one's to anticipate it.

+domain-modeling: trigger on discussing codebase terminology and on writing or editing a CONTEXT.md or an ADR directly, replacing the narrower "pin down domain terminology or a ubiquitous language" / "record an architectural decision" phrasing. Also drops the "another skill needs to maintain the domain model" caveat — that's the invoking skill's job to state explicitly, not this description's.

 ## What it does
 
-`grill-me` takes a **loose idea** and interviews you until it has real decisions in it. You do not need a worked-out plan to start — producing one is what the [session](https://www.aihero.dev/ai-coding-dictionary/session) is for. It asks in **rounds**: each round is the whole **frontier** — every question whose prerequisites you have already settled — so you are never asked something that hinges on an answer it hasn't heard yet.

 It is **[stateless](https://www.aihero.dev/ai-coding-dictionary/stateless)**. It writes no files and leaves no workspace behind. The only thing it leaves is a sharper version of the idea, in your own head.
