feat(apple): explicit input-capture state machine — no more cursor grabs on window chrome
Capture used to engage whenever the app became active, so the click that activates the
window — on the title bar (a drag) or a resize edge — got the cursor warped away
mid-gesture, and raw deltas kept streaming to the host while the user fought the window.
Reworked Moonlight-style, with capture as a deliberate, reversible state owned by
StreamLayerView:

- Engage: automatically once when the stream starts / trust is confirmed (one-shot, can
  never fire surprisingly later), or by clicking into the video (that click's
  press/release are suppressed toward the host; acceptsFirstMouse makes it one click
  from another app). NEVER on app re-activation.
- Release: ⌘⎋ (toggles, key-window-scoped), focus loss — now including same-app window
  switches (⌘, / ⌘N / ⌘M resign key without resigning the app; previously the new
  window inherited a hidden frozen cursor and its typing was double-delivered to the
  host) — and disconnect.
- While released: nothing is forwarded (InputCapture.forwarding gates the GC handlers;
  held keys/buttons are flushed host-side so nothing sticks), the cursor is free, and
  the HUD (now showing the capture state) is clickable.
- The no-beep behavior moved from the NSEvent monitor to first-responder key
  consumption — swallowing at the monitor risked starving GC's own delivery (the
  "input broken altogether" report). The monitor now only intercepts ⌘⎋.
- Adversarial-review fixes: a second session preempts the previous one cleanly instead
  of leaving it captured with dead GC handlers (onPreempted); the engage click's
  suppression latch can't outlive the click (mouseUp backstop); ⌘⎋'s physical Esc can't
  type into the host in either toggle direction (suppressedVK latch + Esc-while-⌘
  guard); capture callbacks defer out of the SwiftUI update pass.

Validated live against the box: 16185 input datagrams injected during a captured
session (gamescope EIS), title-bar drag/resize free while released, and visible
cursor + typing on a streamed KWin desktop, all user-confirmed.
