🧪 Testing Improvement: Add missing error test for yaml load block

[hahwul]

🎯 What: The task involved addressing a missing testing gap in scripts/erb.rb:150 where an exception is rescued when YAML.load encounters an error processing an invalid YAML file within the weapons/ directory.

📊 Coverage: A new test case was added to test/erb_test.rb using Minitest that simulates an invalid YAML file alongside a valid YAML file. The test confirms that the invalid file parsing throws an error, which the script captures, preventing execution abort. The valid YAML file follows and processes successfully, contributing to building the README.md file properly.

✨ Result: Test coverage reliably spans an edge-case to improve resilience and code integrity. The test suite correctly creates an isolated temporary directory rather than operating on live repository records.
