[Bug] ClaudeFilePathFilter crashes on Windows and breaks terminal selection highlight

Plugin version: 0.1.13-beta
IDE: PhpStorm 2025.2.5 (also affects other JetBrains IDEs)
OS: Windows 10/11

---

What's Wrong?

There are two issues in ClaudeFilePathFilter:

Issue 1: Plugin crashes on Windows

The ClaudeFilePathFilter crashes when terminal output contains characters that are illegal for Windows file paths (:, >, <, |, ", ?, *). This happens because Path.resolve(filePath) is called in findMatches$lambda$2() without validating that the matched string contains only valid path characters.

Common triggers:

• URLs in terminal output (e.g., PowerShell upgrade notice containing https://aka.ms/PSWindows)
• Claude Code autocomplete suggestions prefixed with > (e.g., > @filename.php)

Issue 2: Selection highlight broken on file autocomplete

When using the @ file completion feature, suggested file paths are rendered as hyperlinks by ClaudeFilePathFilter. This hyperlink styling (blue, underlined) overrides the terminal's native selection highlight, making it impossible to see which file is currently selected when navigating with arrow keys.

Folders highlight correctly because they don't match the FILE_PATH_PATTERN regex, but files with extensions do match and lose their selection visibility.

What Should Happen?

What Should Happen?

Issue 1:

The plugin should gracefully handle strings containing invalid path characters instead of crashing. Either:

• Validate the string before calling Path.resolve() and skip invalid paths
• Wrap Path.resolve() in a try-catch block for InvalidPathException

Issue 2:

Autocomplete suggestions (indented lines starting with spaces) should not be converted to hyperlinks. This would preserve the terminal's native selection highlight while still providing clickable hyperlinks for actual Claude Code output like Read(file.php).

2. Open Claude Code in the JetBrains terminal
3. Trigger any terminal output containing :, >, <, |, ", ?, or * characters

4. Result: Plugin throws InvalidPathException and crashes

Issue 2 - Selection highlight:

1. Open Claude Code in JetBrains terminal
2. Type @ followed by part of a filename (e.g., @insolv)
3. File suggestions appear as blue hyperlinks

Additional Information

Suggested Fix

For Issue 1:

In findMatches$lambda$2(), add validation before Path.resolve():

val filePath = pathGroup.value

// Skip strings with invalid Windows path characters
if (filePath.contains(":") || filePath.contains(">") || filePath.contains("<") ||
    filePath.contains("|") || filePath.contains("\"") || filePath.contains("?") ||
    filePath.contains("*")) {
    return null
}

For Issue 2:

In applyFilter(), skip indented lines:

// Don't create hyperlinks for autocomplete suggestions (indented lines)
if (line.startsWith(" ") || line.startsWith("\t")) {
    return null
}
