Detect when a new worktree branch would conflict with an existing local branch (e.g. creating "feature/login" when "feature" already exists). - Backend: add findLocalBranchPrefixConflict in git.ts to check all prefix segments before git worktree add -b - Frontend: add findBranchPrefixConflict in branch-name.ts with createMemo caching; disable submit and show inline error when prefix conflicts - BranchPrefixField: accept error prop, show red border + error text Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
Prevents creating worktree branches whose prefix path conflicts with an existing local branch. For example, if branch
featurealready exists, the user can no longer createfeature/login/task-abc123.Changes
electron/ipc/git.ts): AddfindLocalBranchPrefixConflictwhich checks all prefix segments of the target branch name against existing local branches viagit rev-parsebefore runninggit worktree add -b.src/lib/branch-name.ts): AddfindBranchPrefixConflictto detect conflicts using the in-memory branch list, andbranchPrefixConflictErrorfor shared error message formatting.src/components/NewTaskDialog.tsx): Wrap conflict detection increateMemofor efficiency; disable submit button and show inline error when a conflict exists.src/components/BranchPrefixField.tsx): Accepterrorprop, render red border and error text.How it works
Git stores branches as ref files under
.git/refs/heads/. A branch namedfeaturecreates a file at that path, which blocks any branch whose name starts withfeature/(e.g.feature/login). This PR detects that condition both in the UI (early, with memoization) and at the backend (as a safety boundary).Test plan
