fix: Fix version content validation loop logic and improve test coverage
- Fix critical indentation issue where version checking ran outside the test loop - Remove redundant _check_version_content_format function for cleaner logic - Ensure version content validation runs for each test individually - Improve regex patterns with word boundaries for more precise hash detection - Add comprehensive test coverage for SHA hashes, mixed scenarios, and edge cases - All new tests now pass correctly after fixing the loop structure Related to: nf-core/modules#6505 Fixed in: #3676 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
