Greptile Summary

This PR introduces lazy loading of file trees and .gitignore-based filtering for the file explorer and search functionality. The changes shift from hardcoded ignore patterns to respecting project-specific .gitignore files, improving performance and allowing visibility of previously hidden files like _layout and .env.

Key Changes:

• Implemented lazy loading for file tree expansion - directories now load children on-demand rather than loading the entire tree upfront
• Integrated ignore package to parse and apply .gitignore patterns during file listing and content search
• Removed node_modules from hardcoded ignore lists since it's now handled via .gitignore
• Added recursive parameter to fsList API to support non-recursive directory listings
• Enabled showHiddenFiles: true to display dotfiles and directories starting with .
• Introduced constructSubRoot helper function to handle path construction with proper separator detection

Issues Found:

• Line 445 in FileTree.tsx has a filtering bug that could remove sibling directories when loading children
• The worker thread doesn't parse .gitignore, so large ignored directories like node_modules are still traversed (performance impact)

Confidence Score: 3/5

• This PR requires fixes before merging due to a path filtering bug
• The lazy loading implementation is well-designed and the gitignore integration is sound, but there's a critical bug in FileTree.tsx line 445 that filters files incorrectly. The worker performance concern is a secondary issue that should be addressed for optimal performance.
• Pay close attention to src/renderer/components/FileExplorer/FileTree.tsx - the filtering logic at line 445 needs correction
