Context

The git panel's context menu caused visual jitter (flickering/jumping) when opened via right-click on a tracked file. The root cause was in dispatch_context(): it used self.focus_handle == focused to check if the panel itself was directly focused, but when a context menu opened, focus moved to the menu (a child element), causing the "menu" and "ChangesList" key contexts to be dropped. This triggered a re-render with different keybindings, which re-added them, creating a loop of jitter.

The fix replaces the direct focus equality check with self.focus_handle.contains_focused(window, cx), which returns true when any child element (including the context menu) holds focus within the panel's focus tree. This is consistent with how other panels (project panel, outline panel, collab panel) handle focus-based dispatch contexts.

Closes #51813

How to Review

This is a small, focused change in a single file: crates/git_ui/src/git_panel.rs.

1. The fix (~line 974): dispatch_context() method — the old code checked direct focus equality (self.focus_handle == focused), the new code uses self.focus_handle.contains_focused(window, cx) and restructures the conditionals so CommitEditor is checked first via if/else if.
2. The test (~line 7871): test_dispatch_context_with_focus_states — verifies 4 focus state transitions: commit editor focused, changes list focused, back to commit editor, and back to changes list. Each case asserts the correct key contexts are present/absent.
