Greptile Summary

This PR updates CodeMirror language detection for file paths. The main changes are:

• Lower-priority plain Text fallback matching.
• Later-registered modes winning equal-specificity matches.
• Extra filename mappings for shell, properties, JSON, YAML, TOML, and protobuf files.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.

Important Files Changed
