A query submitted from the companion remote now behaves like a submit
instead of focus-to-type: TvKeyboardController closes an already-open
OSK and lands focus on the input without reopening it, then the shared
handleSearchSubmit path runs the search and focuses the first result.
Also guard DebouncedMediaSearch against selection-only controller
notifications re-arming the debounce into a duplicate fetch.

Backing out to home selected the home tab but let focusActiveTabIfReady
steal real focus into the content while _isSidebarFocused stayed true,
leaving the rail stuck expanded over a shifted content box that clipped
the end of every hub row. Skip the content-focus grab while the sidebar
owns focus, move the sidebar focus ring to the Home item on back-to-home,
and self-heal the flag whenever the content scope actually gains focus.

Guest switch dispatch pre-marked its dedup key and fired-and-forgot, so
any failure (fetch error, reload busy with an auto-advance, navigation
race with the host exiting) silently stranded the guest on the old media.
A CurrentPlaybackDispatcher now marks a key handled only after the sink
reports success against the committed identity, with a serialized
in-flight slot, timeout, and generation reset; the reconciler re-offers
unattached media on every host heartbeat, making the heartbeat the retry
channel. Fetches that outlive their dispatch are re-validated against the
current snapshot so a stale switch can't override the live one.
hostExitedPlayer now rides the controller's ordered message queue with
host authentication instead of racing state handling in the provider.
The side-nav host's onSystemBack called _handleMainBack on the system
route-pop path, jumping straight to the home tab and skipping the dpad
back chain (content -> top tabs -> sidebar). Restore the original inert
behavior: canPop:false blocks the route-pop and the key path owns the
chain; the host still closes an open sheet on back. Bottom-nav unchanged.
Both main_screen hosts (side-nav + bottom-nav) drop their PopScopes and
pass canPop:false + onSystemBack to OverlaySheetHost, so a system back
with a sheet open closes the sheet instead of running tab-nav/exit. Key
(dpad) back path unchanged; onSystemBack mirrors it for a pure popRoute.
