Firefox, Safari and WebKitGTK have no Capability Delegation, so the host
can't start a share from its call bar: getDisplayMedia needs the click in
this frame. Until now the host clicked EC's hidden footer button through
the DOM, which only works while the frame is same-origin.
With lotusHostControls + lotusFrameScreenshare the fork now shows EC's own
screenshare button (floating bottom-right, footer still hidden), so the
click is native. controls_state reports frameScreenshare so the host hides
its own button. New toWidget io.lotus.set_frame_screenshare { visible }
lets the host hide it while the room's call policy forbids screensharing
(never while a share is live, so it can still be stopped).

The host used to add PTT/deafen key listeners to this frame's window,
which needs same-origin access. Now it sends `io.lotus.set_hotkeys
{ codes }` and the fork reports those keys as `io.lotus.hotkey`
(keydown/keyup with modifiers + whether the target is a text field or a
button), plus window focus changes so a held PTT is released. The
default action is cancelled here with the host's rules (not while typing,
not on a focused button). `controls_state` carries `hotkeys: true`.
Fixes a live bug: EC's own shortcuts (M = toggle mic, Space = PTT) also
fired for the host's keys, so with focus in the call and the default
deafen key M, the first press turned the MIC ON instead of deafening
(even in push-to-talk mode). EC's shortcuts now ignore keys the host owns.

toWidget `io.lotus.set_screenshare { on?: boolean }` (omit to toggle)
starts/stops sharing via the view model instead of the host clicking EC's
hidden button. The host sends it with Capability Delegation
(`delegate: "display-capture"`) where supported, so getDisplayMedia keeps
the user's click on engines that require it. `controls_state` now carries
`screenshareAction: true` so the host only uses it on a fork that has it.

The Lotus host drove these by clicking EC's hidden controls in our DOM and
read screenshare/layout state from it, which only works while the frame is
same-origin and breaks whenever a data-testid changes. New actions:
- toWidget io.lotus.set_layout { layout: "grid" | "spotlight" } → the layout
switch view model's setLayout.
- toWidget io.lotus.open_settings { open?: boolean } → setSettingsOpen
(toggle when `open` is omitted).
- toWidget io.lotus.toggle_reactions → a window event the reactions button
listens for.
- fromWidget io.lotus.controls_state { screensharing, layout } on change; its
arrival tells the host the fork supports the actions above.
Screensharing stays host-driven for now: getDisplayMedia needs the user's
click to reach this frame (Capability Delegation), which a widget message
doesn't carry.
