Raise pr-review job timeout to 30 minutes (#108)

## Why

The reviewer model is now `claude-opus-5`, which runs longer per review
than opus-4-8 (and the automatic cybersecurity→opus-4.8 safety fallback
can stack a second run into the same job). On the ductone side the same
model bump drove judge PR-review timeouts from 0/809 runs to 20/191
(10.5%) against a 15-minute cap — cancelled mid-review, surfacing as a
"did not finish in time … not a verdict" notice rather than a real
verdict. This raises the caps here before the same regression shows up.

## What this changes

Raises `timeout-minutes` to 30 on both PR-review reusable-workflow jobs:
`pr-review.yaml` (15→30) and `general-pr-review.yaml` (20→30).
Trade-off: a longer-running or wedged review now uses up to 30
runner-minutes before being cut off.
