[feature] Extend noise entry detection for issue 265

[paul-fresquet]

Summary

This PR completes issue #265 by extending noise entry handling in inventory analysis.

Key changes

• Added additional noise entries in the embedded resource list ($RECYCLE.BIN, .AppleDB, .AppleDesktop).
• Added non-root noise directory filtering in inventory traversal.
• Renamed skip reason NoiseFile to NoiseEntry to cover both files and directories.
• Updated and extended unit tests for detector and inventory builder behavior.
• Updated noise detection specification documentation.

Notes/Risks

• macOS behavior intentionally remains case-insensitive (documented deviation from strict issue wording).
• Root inventory parts are still analyzed even if their root name matches a noise directory pattern.

Closes #265

Pull request overview

Extends the client inventory “exclude system files” feature to treat additional OS-generated entries as noise (including directories) and updates the corresponding tests and specification.

Changes:

• Expanded the embedded noise entries list (e.g., $RECYCLE.BIN, .AppleDB, .AppleDesktop).
• Added inventory traversal logic to skip non-root noise directories and record them as skipped entries.
• Renamed skip reason from NoiseFile to NoiseEntry and updated unit tests + spec.
