Greptile Overview

Greptile Summary

This PR updates the repository’s pinned Ruby version from 3.1.4 to 3.4.8 (via .ruby-version) and aligns the GitHub Actions release workflow to run with Ruby 3.4.8.

The changes are isolated to version pins; no library/runtime code is modified, and the release workflow continues to use ruby/setup-ruby@v1 with Bundler caching and the existing test step.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk.
• The change only bumps Ruby version pins in .ruby-version and a single GitHub Actions workflow input. No application/library logic changes were introduced, and the workflow continues to use standard ruby/setup-ruby + bundler caching.
• No files require special attention
