August 2025 (2025-08) monthly summary for tarantool/tt: Strengthened code quality gating and CI reliability with minimal impact on PR workflows. Implemented Markdown linting in pre-commit and adjusted rules to ignore PR template files in .github to preserve formatting while enforcing documentation quality. Fixed CI flakiness by conditionally skipping flaky 'follow' tests in CI, reducing false negatives and build noise. These changes improve documentation consistency, reduce CI churn, and accelerate contributor feedback.
