fix: make editor and kanban views mutually exclusive

[rabanspiegel]

Summary

• Toggling kanban while in editor now closes editor first (and vice versa)
• Going home or switching projects resets view state to default
• Consolidated inline toggle handlers into proper callbacks

Test plan

• Open editor, click kanban button → should switch to kanban
• Open kanban, click editor button → should switch to editor
• From editor, click home → should return to home view
• Switch projects while in editor → should reset to default view

---

Note

Ensures UI modes don’t conflict and cleans up state on navigation.

• Editor/Kanban exclusivity: Centralized handleToggleKanban and new handleToggleEditor so toggling one closes the other; updated bindings in AppKeyboardShortcuts and Titlebar.
• View state resets: Clear showEditorMode/showKanban when going home, activating a project, and only when switching tasks across different projects.
• Git IPC hardening (src/main/ipc/gitIpc.ts): git:get-branch-status now validates path, early-exits for non-repos, improves default branch detection and ahead/behind computation, and adds clearer logging.
