[feature] Extend noise files list with common OS-generated files

[paul-fresquet]

Summary

Extend the list of known "noise files" that are automatically excluded when the user enables the "Exclude system files" option. The current list is minimal and misses many common OS-generated files.

Current State

The current implementation only excludes 5 files:

var isCommon = fileInfo.Name.In("desktop.ini", "thumbs.db", ".desktop.ini", ".thumbs.db", ".DS_Store");

Proposed Extended List

Windows

File	Purpose
desktop.ini	Folder customization settings
thumbs.db	Thumbnail cache
ehthumbs.db	Windows Media Center thumbnail cache
ehthumbs_vista.db	Vista Media Center thumbnail cache
$RECYCLE.BIN	Recycle bin folder

macOS

File	Purpose
.DS_Store	Finder folder metadata
.AppleDouble	Resource fork storage
.LSOverride	Launch Services override
.Spotlight-V100	Spotlight search index
.Trashes	Trash folder on volumes
.fseventsd	File system events daemon data
.TemporaryItems	Temporary items folder
.VolumeIcon.icns	Custom volume icon
.AppleDB	Apple database files
.AppleDesktop	Apple desktop database

Linux

File	Purpose
.directory	KDE/Dolphin folder metadata

Acceptance Criteria

• Update the noise file list in FileSystemInspector (or new NoiseFileDetector)
• Use case-insensitive comparison for Windows files
• Use case-sensitive comparison for macOS/Linux files
• Add inline documentation explaining each file's origin
• Unit tests verifying detection of all listed files
• Consider both file names and directory names (e.g., .Spotlight-V100 is a directory)

Technical Notes

• Some entries are directories (.Spotlight-V100, .Trashes, $RECYCLE.BIN)
• The noise filter should apply to both files and directories
• Consider using a HashSet<string> for O(1) lookup performance

Priority

Standard — Improves user experience by reducing clutter in inventories.
