Greptile Summary

This is a routine dependency bump from dependabot that updates the minimum required version of the ruff linter/formatter in the dev extras of pyproject.toml from >=0.15.11 to >=0.15.15.

• The change is limited to a single version bound in pyproject.toml; no code or configuration is modified.
• Ruff 0.15.12–0.15.15 contain only bug fixes (e.g., a pyflakes F821 correction around function-scope bare annotations), performance improvements, and documentation updates — no breaking changes.

Confidence Score: 5/5

Safe to merge — only the minimum version bound for a dev-only linter tool is changed, with no impact on production code.

The change is a single-line version bump to a dev-only tool (ruff). The intermediate releases contain only bug fixes, performance improvements, and documentation updates with no breaking changes, so there is no realistic risk of regressions.

No files require special attention.
