Greptile Summary

This PR bumps the concurrent-ruby gem from 1.3.3 to 1.3.7, resolving three low-severity CVEs (CVE-2026-54904, CVE-2026-54905, CVE-2026-54906) related to livelock, lock-count overflow, and wrong-thread lock release.

• The Gemfile constraint is widened from < 1.3.4 to < 1.3.8, allowing the patched release while keeping the upper bound tight.
• Gemfile.lock is updated consistently with the new resolved version and matching constraint entry.

Confidence Score: 5/5

Safe to merge — a minimal, automated dependency bump that applies security patches with no functional or API changes.

The only changes are the version constraint in Gemfile and the resolved version in Gemfile.lock. The upstream release addresses three low-severity concurrency bugs in rarely-exercised code paths; v1.3.7 is a drop-in replacement with no breaking API changes. The upper-bound constraint is kept tight (< 1.3.8), limiting exposure to future unknowns.

No files require special attention.

Important Files Changed

Filename	Overview
Gemfile	Version constraint widened from < 1.3.4 to < 1.3.8 to allow the security-patched 1.3.7 release.
Gemfile.lock	Resolved version of concurrent-ruby bumped from 1.3.3 to 1.3.7; DEPENDENCIES section updated to match the new constraint.
