Tag @claude in PR review comments to compound CLAUDE.md rules

The problem

Code review nits die in the PR thread. The next Claude session repeats the same enum, naming, or style mistake.

The hack

Install with `/install-github-app`, then in a review comment write the nit and `@claude add to CLAUDE.md …`. Claude updates project memory as part of the review.

Why it works

Anthropic calls this compounding engineering: each correction makes every future session better, and PR review is the highest-signal place to capture it.

Setup

1. In Claude Code, run `/install-github-app` and finish GitHub setup. 2. On a PR, comment e.g. `nit: prefer string literal unions over enums @claude add to CLAUDE.md`. 3. Confirm CLAUDE.md updated on the branch. 4. Make this a team norm for recurring nits.
