Problem

With "Keep groups sorted alphabetically" on, sortGroups ends by calling tabs.move(id, { index: -1 }) on every ungrouped tab. In Firefox, a tab moved to the end of the strip is absorbed into the group that sits last there. Result: single-site tabs that never reached the minimum join an unrelated group (for example, the alphabetically last one). Each close also re-moves every ungrouped tab, which reshuffles them.

Change

• Remove moveUngroupedTabsToEnd and its call. Ungrouped tabs are never passed to tabs.move.
• Move groups with an explicit target index: each group goes after the tabs of every group placed before it (pinnedCount + cumulative sizes). A plain index: pinnedCount + i would land inside an earlier multi-tab group and split it in Firefox.
• Groups now sit at the left of the strip in alphabetical order; ungrouped tabs keep their relative order after them.
• Tests: ungrouped tabs are never moved; multi-tab group indexes; pinned tabs offset.

Testing

• vitest run: 965 passed on this branch (based on current master).
• tsc --noEmit and biome check on the changed files: clean.
• Manual: Firefox Developer Edition, auto-grouping on and off, groups of 2–4 tabs plus singles, sort on. Groups stayed intact and singles stayed ungrouped in their original order.

Open question for maintainers: the sort now puts groups on the left instead of the right. Happy to flip the direction if that's a problem.
