# Objective

The Git Panel exposes the `ChangesList` key context while its list is
focused, including when the History tab is active. This causes
Changes-only keybindings to match in History and provides no context for
History-specific bindings.

This is a fresh submission of the revised change from #63669, as
requested in that PR's discussion.

Fixes #61012

## Solution

Select the list key context from the active Git Panel tab. Changes
exposes `ChangesList`, while History exposes `HistoryList`. The shared
`GitPanel` and `menu` contexts remain unchanged.

Preserve compatible keyboard behavior by sharing navigation,
confirmation, and cancellation bindings between `ChangesList` and
`HistoryList` on macOS, Linux, Windows, and Vim. File, staging, restore,
and commit-editor bindings remain exclusive to `ChangesList`.

Extend the dispatch-context test to verify that the list contexts are
mutually exclusive and absent while the commit editor is focused.

## Testing

- `cargo fmt --package git_ui -- --check`
- `./script/check-keymaps`
- `git diff --check`
- `cargo test -p git_ui test_dispatch_context_with_focus_states --
--nocapture`
- `cargo test -p git_ui` (153 passed)
- `cargo build -p zed`
- Manually verified on macOS that History reports `HistoryList` without
`ChangesList`, arrow navigation selects commits, and Enter opens the
selected commit
- Linux and Windows keymaps were updated and checked, but not manually
exercised on those platforms

## Showcase

The Keyboard Context view shows `GitPanel`, `menu`, and `HistoryList`
while the History tab is focused. `ChangesList` is absent.
