ci: refresh audited root action pin

[roli-lpci]

Summary

• pin the root action example to the exact dependency-refresh merge commit
• keep README, SECURITY policy, and the executable example synchronized

Verification

• actionlint .github/workflows/example-usage.yml
• no stale audited self-pin remains in README, SECURITY.md, or .github

Supersedes #30, whose proposed pin predates the dependency refresh.

Warning

Review limit reached

@roli-lpci, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 51 minutes

Limit details: You’ve used all 3 included reviews currently available.

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits within each organization.

For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window.

Please refer docs for additional details.
