feat: eval prints its origin URL, type --focused, AGENT_BROWSER_HUMANIZE bogus warn

- eval now prints `eval @ <url>` to stderr (stdout stays the raw value) so an
  agent can catch tab drift — e.g. a logged-in fetch that hit the wrong origin —
  before trusting the result. Mitigates the issue #2/#3 P0 safety concern. (eval
  already returned the origin; the default output just never surfaced it.)
- `type --focused <text>`: type into the currently-focused element with no
  selector, for custom widgets that move focus to a hidden input (issue #2 P3).
- AGENT_BROWSER_HUMANIZE set to an unrecognized value now warns once (like the
  --humanize flag) instead of being silently ignored (Hermes #3).
