* feat(computer): drive macOS apps in the background by default
Clicks no longer activate and raise the target first. Pointer and key
input go to the target window's pid through a new BackgroundInputTransport:
mouse and scroll events carry the window id in field 51 and a window-local
location, keys run inside a focus-without-raise key-window scope, and
chords carry no Unicode string so menu key equivalents fire. Scroll and
drag now land (#27306); typed text no longer doubles in Electron (#17942).
The HID tap and focus fence stay for --restore-window only. Results
report action.delivery, the handshake reports supports.input.background,
and a missing private symbol or a popup click fails with
background_unavailable instead of falling back to the foreground.
* test(computer): read typed key strings back instead of diffing live-state events
* fix(computer): keep Unicode characters in one key event
* fix(computer): preserve active macOS key windows
Refuse key-window changes in the active app and surface failed
focus records, including cleanup after partially delivered input.
* fix(computer): guard macOS click routes before delivery
* fix(computer): let paste events read the clipboard
* fix(computer): classify clicks in the requested macOS window
* fix(computer): fence macOS scroll and drag recipients
