stagent v0.11.0

Added

• Host screen (ホストの画面, ADR 0008): host_screen.list,
  host_screen.start, host_screen.ack, host_screen.stop and the
  notifications host_screen.frame and host_screen.state show a page of
  a browser an agent drives in an app tab, over the tab's own bridge. The
  browsers listed are the user's Chromium-family browsers started with
  --remote-debugging-port (0 read from DevToolsActivePort), each
  port checked with /json/version, with their page targets and the tool
  told by the profile path. A page is shown with one
  Page.captureScreenshot and then Page.startScreencast (JPEG, quality
  70); at most two frames wait for the app's ack, of the frames taken
  meanwhile only the newest is kept, and a stalled app gets the
  screencast paused and resumed with a full frame. Served to bridges
  under a coding agent too (#640).
• host_screen.list: a browser started with --remote-debugging-pipe
  only is listed with connectable: false and reason: "pipe_only"
  (with its tool), and cdp_ports names ports on 127.0.0.1 by hand: each
  that answers /json/version as CDP is listed with manual: true, in
  one item with a browser found on the same port; a port outside 1–65535
  is bad_request (#642).
• Host screen: Android emulators. host_screen.list has an android
  section: the emulators of adb devices -l (never a physical device),
  matched by serial with the files they advertise their gRPC port in
  (avd/running/pid_<pid>.ini), with the AVD name; one without gRPC
  (started with -port only) is connectable: false, reason: "no_grpc", and a host without adb gets missing: {code: "adb_not_found"}. host_screen.start {target: {kind: "android", serial}} shows the emulator through its gRPC streamScreenshot
  (Bearer grpc.token, RGB888 at half resolution, encoded to JPEG
  quality 70); width and height are the display's px and swap when
  it turns, and a stopped emulator sends state: "gone" (#643).
• Host screen of an iOS simulator (macOS only, capability
  host_screen_ios): host_screen.list has an ios section with the
  booted iOS simulators (xcrun simctl; missing xcode_not_found
  without Xcode, simctl_failed with simctl's error as the message when
  it fails or runs out of time, a simulator companion_not_found without
  idb_companion), and host_screen.start {target: {kind: "ios", udid}}
  shows one through an idb_companion started for the stream on a private
  Unix socket (no TCP port): its MJPEG video_stream (half resolution,
  quality 0.7, redrawn screens only), sized in points. The companion is
  stopped with the stream (stop, another start, the bridge exiting;
  --idle-shutdown-time should stagent die), and a simulator shut down
  sends state: "gone". Other hosts answer unsupported (#645).
• host_screen.input operates the page shown: tap, drag, scroll,
  text and navigate (back, forward, reload, url), points as
  fractions of the frame turned into CSS px with the screencast's
  metadata (deviceWidth, deviceHeight, offsetTop,
  pageScaleFactor). A browser gets only Input.* (insertText for
  text in any script, an Enter key event for enter), Page.navigate,
  Page.reload and the history's Page.getNavigationHistory and
  Page.navigateToHistoryEntry; key is unsupported. Inputs
  run in order on start's queue while acks are answered at once, so a
  slow input never stops the frames (#641).
• host_screen.input operates an Android emulator: tap, drag and
  scroll (one swipe from the cursor) through gRPC sendTouch in the
  display's px, turned back with the emulator's rotation; key back,
  home, recents through adb shell input keyevent (works with
  hw.keyboard=no, no gRPC sendKey); text through adb shell input text when printable ASCII, else gRPC setClipboard and
  KEYCODE_PASTE, with KEYCODE_ENTER for enter. navigate is
  unsupported (#644).
• host_screen.input operates an iOS simulator: tap, drag, scroll
  (one swipe from the cursor), text of ASCII and key: "home", as HID
  events on the stream's idb_companion hid stream, kept open and
  reopened when the companion ends it (no program per input). Points are
  fractions of the frame in pt; text is typed as key presses of a US
  keyboard (Shift for capitals and the upper symbols), enter as Return.
  back, recents, navigate and text with a character other than
  ASCII (Japanese input is pending, #649) are unsupported. A drag cut
  short (the bridge ending) lifts its touch, and stopping the stream lets
  the companion perform what was sent (up to a second) before stopping
  it (#646).
