[BUG] ClaudeFilePathFilter crashes on Windows with commands starting with "/"

What's Wrong?

The ClaudeFilePathFilter crashes when parsing Claude Code terminal output on Windows, specifically when commands start with /. The filter attempts to parse the prompt character > as part of a file path, which is invalid on Windows. It's happening since 0.1.13-beta release.

What Should Happen?

The file path filter should:

• Ignore the Claude Code prompt (>) when detecting file paths
• Validate paths before attempting to parse them
• Not crash on invalid path characters
