Case-sensitive directory preservation in project reconstruction

[Mabbs]

Description

During project reconstruction, the current implementation only preserves directories with all-lowercase names (e.g. movie, audio). Some RPG Maker games use capitalized directory names (e.g. Movie, Audio). This causes these directories to be omitted during decryption/reconstruction, potentially breaking game assets.

Expected Behavior

Directory preservation should be case-insensitive. Both audio and Audio should be recognized as valid directories when reconstructing projects.

Suggested Solution

Modify the directory preservation logic to:

1. Compare directory paths case-insensitively
2. Preserve original casing in output filesystem

Affected Paths (Examples)

• Movie/ → Currently ignored
• Audio/ → Currently ignored
