PackCheck v3.1.2

New

• MSI installer: choose the install folder (Custom → Browse), optional desktop shortcut (on by default), optional start with Windows, and a "Launch PackCheck" box on the last page. Upgrades keep the folder you chose.
• Backups: delete a backup from the Backups tab (with confirmation).

Fixed

• Plugins page: the category box showed "CategoryOption { Key = ... }" instead of the category name.
• Assistant with Google Gemini: the first tool call failed with "HTTP 400 ... missing a thought_signature". The signature Gemini sends with each tool call is now passed back as required.

Other

• New project website: https://x1npar1.github.io/PackCheck/ (one page, product tour, FAQ)
• README animations play at their real speed.
