Quiver v2.3.13

Fixes Windows installs for GitHub releases that ship .tar.gz assets (for example Project Picori / Minish Cap decomp).

Install / extraction

• Windows tar.gz installs — Game installs now extract .tar.gz with the system tar tool (same approach as Linux/macOS and the CLI updater), instead of the broken custom Windows tar reader that could fail with “Could not find any recognizable digits.”
• Managed fallback — If system tar cannot be started, a corrected built-in extractor is used (no double-read of block padding; size fields trim spaces).
