terminal: Bind Alt+F4 to Close Window in the terminal keymap

[SAKETH11111]

Closes #52774

Summary

• Bind Windows Alt+F4 to workspace::CloseWindow in the Terminal keymap context
• Add a regression test covering the built-in Windows terminal keymap entry

Why

When the integrated terminal is focused, Alt+F4 should close the window instead of falling through to terminal keystroke handling. Handling this in the Windows Terminal keymap keeps the fix aligned with the rest of the terminal shortcut overrides.

Validation

• cargo test -p settings windows_terminal_keymap_closes_window_on_alt_f4

Release Notes:

• Fixed Alt+F4 on Windows so Zed closes even when the integrated terminal is focused.

Looks like you have an unrelated commit in your branch?

Also, is it possible to just do this using a default keybind in the Terminal context?

[SAKETH11111]

Thanks for calling both of these out. I rebased the branch onto main to remove the unrelated commit, and I reworked the fix to use the Windows Terminal keymap context instead of special-casing TerminalView. The PR now binds Alt+F4 to workspace::CloseWindow in that context and adds a regression test that checks the built-in Windows keymap entry. Validation: cargo test -p settings windows_terminal_keymap_closes_window_on_alt_f4.

Also passing by and noting that crates/settings/src/keymap_file.rs is somewhat odd, we do not have other tests like these and do not seem to need one.

I'll leave the decision about the binding to @\reflectronic .

Agreed about the test - removed. The binding looks fine to me tho.
