Subject: [PATCH] feat: Warn when binding browser-reserved shortcuts (#9406)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

Show a non-blocking warning in the keybinding edit dialog when users try
to bind shortcuts that browsers intercept (e.g. Ctrl+T, Ctrl+W, F12).

## Changes

- **What**: Add `RESERVED_BY_BROWSER` set of known browser-intercepted
shortcuts, `isBrowserReserved` getter on `KeyComboImpl`, and a warning
`<Message>` in the keybinding edit dialog. Users can still save the
binding.

## Review Focus

Whether the list of browser-reserved shortcuts is comprehensive enough,
and whether a non-blocking warning (vs blocking) is the right UX choice.

## Before

## After
