github: LLM-review: stop reviewing new PRs automatically

Drop the pull_request_target trigger so the LLM review no longer runs
on opened/reopened PRs. We are limited to 15 Claude routine runs per
day, and the automatic per-PR trigger exhausted that budget on
several days, starving the nightly digest.

The nightly schedule and manual workflow_dispatch triggers remain.
