🗣️ Foreword

Thanks for taking the time to read this feature request.

:person_frowning: Problem Statement

When creating a new task, the base branch is chosen from a native <select> dropdown (src/components/NewTaskDialog.tsx). With a large number of branches this is slow to navigate — you cannot type to filter, only scroll the full list. Repos with dozens of branches make picking the right base branch tedious.

❔ Possible Solution

Replace the native <select> with a searchable combobox:

• A text <input> that filters the branch list as you type (case-insensitive substring match).
• A dropdown list of matching branches below the input; selectable by click or arrow keys + Enter.
• Keep the existing baseBranch() signal as the source of truth.
• No backend change required — branch data already comes from IPC.GetBranches (git branch --list).

⤴️ Describe alternatives you've considered

• Keeping the native <select> and relying on the browser's type-ahead — limited (matches only from the start of the option text, resets quickly, no visible filtering).

➕ Additional context

Scoped to the "New Task" dialog branch picker. No new IPC channel needed.
