📝 Walkthrough

Walkthrough

Adds five git helper functions (discard/stash/pop), re-exports them, exposes TRPC endpoints in the staging router, and wires stash/discard UI controls, dialogs, and mutations into ChangesView and ChangesHeader.

Changes

Cohort / File(s)	Summary
Git Helper Functions apps/desktop/src/lib/trpc/routers/changes/security/git-commands.ts	Adds five async helpers: gitDiscardAllUnstaged, gitDiscardAllStaged, gitStash, gitStashIncludeUntracked, gitStashPop. Each validates worktree, instantiates simpleGit, and runs the corresponding git command.
Module Exports apps/desktop/src/lib/trpc/routers/changes/security/index.ts	Re-exports the five new git helpers from ./git-commands.
TRPC Endpoints apps/desktop/src/lib/trpc/routers/changes/staging.ts	Adds five procedures: discardAllUnstaged, discardAllStaged, stash, stashIncludeUntracked, stashPop. Each accepts { worktreePath: string }, calls the helper, and returns { success: true }.
Changes UI apps/desktop/src/renderer/screens/main/components/WorkspaceView/Sidebar/ChangesView/ChangesView.tsx	Adds mutations for the five operations with success/error toasts, refetch behavior, confirmation dialogs for discards, and passes stash callbacks + pending state to ChangesHeader.
ChangesHeader UI apps/desktop/src/renderer/screens/main/components/WorkspaceView/Sidebar/ChangesView/components/ChangesHeader/ChangesHeader.tsx	Adds optional props onStash, onStashIncludeUntracked, onStashPop, isStashPending; introduces a Stash dropdown and restructures header to surface stash actions and base-branch selector.
Minor UI tweak apps/desktop/src/renderer/.../CategorySection/CategorySection.tsx	Adds group class to header container; minor JSX/comment cleanup.

Poem

🐰
A nibble, a stash, then quiet and neat,
Changes tucked in a pocket, safe and discreet.
Pop them back later with a gentle hop—
Tiny rabbit cheers as the branches stop! ✨
