refactor: rename qa-design-review → design-review

The "qa-" prefix was confusing — this is the live-site design audit with
fix loop, not a QA-only report. Rename directory and update all references
across docs, tests, scripts, and skill templates.

 ## What's new and why it matters
 
-**Design is at the heart.** `/design-consultation` doesn't just pick fonts. It researches what's out there in your space, proposes safe choices AND creative risks, generates realistic mockups of your actual product, and writes `DESIGN.md` — and then `/qa-design-review` and `/plan-eng-review` read what you chose. Design decisions flow through the whole system.

 **`/qa` was a massive unlock.** It let me go from 6 to 12 parallel workers. Claude Code saying *"I SEE THE ISSUE"* and then actually fixing it, generating a regression test, and verifying the fix — that changed how I work. The agent has eyes now.

 Real files get committed to your repo (not a submodule), so `git clone` just works. Everything lives inside `.claude/`. Nothing touches your PATH or runs in the background.
