Garry Tan daf13d822c feat(security): pin JS/eval execution to cookie-imported origins

When cookies have been imported for specific domains, block JS execution
on pages whose origin doesn't match. Prevents the attack chain:
1. Agent imports cookies for github.com
2. Prompt injection navigates to attacker.com
3. Agent runs js document.cookie → exfiltrates github cookies

assertJsOriginAllowed() checks the current page hostname against imported
cookie domains with subdomain matching (.github.com allows api.github.com).
When no cookies are imported, all origins allowed (nothing to protect).
about:blank and data: URIs are allowed (no cookies at risk).

Depends on #615 (cookie domain tracking).

Closes #616
