chore(dev): APEX Review 1Password wrapper + install script
Makes the /audit skill reproducible on any Mac without stashing ANTHROPIC_API_KEY in dotfiles.
- scripts/apex-review-wrapper.sh: pulls the key from 'op://ThioBot/Anthropic API Key/credential' and execs apex-review.real.
- scripts/install-apex-review.sh: idempotent installer that moves the pip shim aside and drops the wrapper into ~/.local/bin.
- README: new 'Dev tooling: APEX Review with 1Password' section.
