Modpack version switch

Install (card and detail) opens a version-picker modal, defaulting to the latest installable version. Launching an instance whose pack has a newer version available prompts to update first. Update reinstalls pack files while preserving saves/config (snapshot before, restore after) — not a finished delta-diff.

Steps

5 of 6 steps

• Install opens a version picker, newest already chosen
• An instance with a newer version out asks once, before it launches
• Worlds untouched; the old config kept beside the new one
• The instance records which version it is
• Going back to an older version, not only forward
• What changed between the two versions, after an update
