Greptile Summary

This PR adds a "Project name" sort option to the left sidebar, persists the new value in SidebarSnapshot, and extends SidebarTaskSortBy with the 'project-name' variant. Alphabetical sorting is implemented via localeCompare with sensitivity: 'base' and numeric: true, with a clean fallback to manual drag order when projectOrder is non-empty.

• sidebar-store.ts: orderedProjects branches on taskSortBy === 'project-name' && projectOrder.length === 0 for alphabetical project sort; applySort('project-name') resets projectOrder to [] to trigger the alpha path.
• projects-group-label.tsx: Adds a "Project name" DropdownMenuRadioItem wired to applySort, consistent with the existing "Created at" and "Last used" items.
• sidebar-store.test.ts: New focused tests verify alphabetical ordering (case-insensitive) and that a subsequent drag reorder takes precedence over the name sort.

Confidence Score: 3/5

The project ordering itself works correctly, but selecting 'Project name' silently changes how tasks within projects are ordered, which is an unintended side-effect that could confuse users.

The compareSidebarTasks function uses taskSortBy directly and only special-cases 'created-at'; with 'project-name' now in the union, it falls into the 'updated' branch and re-sorts all tasks by last-used without any user action or indication. A user who had created-at task sort selected and switches to project-name ordering will silently see their per-project task lists change sort order.

sidebar-store.ts — specifically the compareSidebarTasks method and how it handles the new 'project-name' value of taskSortBy.

Important Files Changed

Filename	Overview
src/renderer/features/sidebar/sidebar-store.ts	Adds alphabetical project sorting via compareSidebarProjects and toggles on empty projectOrder; however, compareSidebarTasks silently falls back to updated-at when taskSortBy === 'project-name', unintentionally changing task sort for users who previously had created-at selected.
src/renderer/features/sidebar/sidebar-store.test.ts	New test file covering project-name sort and manual-order precedence; does not test that task sort within projects is unaffected when project-name sort is active.
src/renderer/features/sidebar/projects-group-label.tsx	Adds a 'Project name' radio item to the sort dropdown; wires onClick to sidebarStore.applySort('project-name') consistently with existing items.
src/shared/view-state.ts	Extends SidebarTaskSortBy union type with 'project-name'; backward-compatible change, old snapshots without this value will parse as undefined and fall back to the default.

   Task sort silently changes to updated-at when "Project name" is selected

   compareSidebarTasks derives kind as this.taskSortBy === 'created-at' ? 'created' : 'updated'. Because 'project-name' is not 'created-at', tasks within every project will be sorted by lastInteractedAt (updated-at) the moment the user picks "Project name" — even if they previously had "Created at" task sort active. A user with created-at task sort who switches to project-name ordering will see their per-project task lists silently re-sorted, with no indication that the task sort changed.

   `compareSidebarTasks` derives `kind` as `this.taskSortBy === 'created-at' ? 'created' : 'updated'`. Because `'project-name'` is not `'created-at'`, tasks within every project will be sorted by `lastInteractedAt` (updated-at) the moment the user picks "Project name" — even if they previously had "Created at" task sort active. A user with `created-at` task sort who switches to project-name ordering will see their per-project task lists silently re-sorted, with no indication that the task sort changed.
