uncompressDirectoryZstd()

bool conscience_utils::compression::uncompressDirectoryZstd	(	const fs::path &	zstdFilePath,
		const fs::path &	targetDirectory
	)

Decompress a .tar.zst archive produced by the compress code above, rebuild files into a target directory.

Algorithm:

1. Read the full .zst file into memory
2. Get original TAR size with ZSTD_getFrameContentSize()
3. Decompress into TAR buffer
4. Parse TAR stream:

• Read 512-byte headers
• Extract file name + size
• Read file data
• Skip padding

1. Stop on two consecutive zero blocks
