Latch v3.3.0

• The stream is the Mac's screen. Match screen is the default: the PC
  is asked for this display's own pixel size, and 1080p, 1440p and 4K now
  cap the long edge while keeping the display's proportions, so nothing is
  letterboxed or stretched. The engine switches the PC's display to the
  size asked for (setup turns its display settings on, and the launch
  request now allows it), and a session reconnects by itself when the Mac
  moves to a different display.
• Nothing lowers the quality for the route any more. Recommended quality
  is 35 Mbps at this screen's size whether the path is direct, through
  your relay or through Tailscale's; a long round trip adds delay, not a
  bitrate or frame-rate cap. The engine's own bitrate ceiling is cleared
  and it is asked to keep frames flowing while the desktop is still. A PC set up
  by an earlier Latch gets the same profile applied once by the service,
  between sessions. The quick profiles are now Smooth (1080p · 60 fps ·
  12 Mbps), Balanced (match screen · 60 · 35) and Sharp (match screen ·
  60 · 65).
• A PC whose only display is the Virtual Display Driver can only switch to
  sizes that driver lists. Setup adds every size a Mac can ask for to its
  vdd_settings.xml (a minimal file when there is none, everything else
  kept) and restarts the display; the setup card says when sizes are
  missing.
• The Mac decoder is checked for hardware acceleration rather than assumed,
  runs in real-time mode, decodes off the packet-receive thread, and the
  window presents with one frame of latency. Stats name the decoder as
  hardware or software.
• One Stream settings panel, in the lobby and during a session: quick
  profiles, picture quality, resolution, frame rate, bitrate target and
  video format, with the exact size, rate and target it adds up to.
  Applying mid-stream reconnects. Stats opens a Stream performance
  window (received against target bitrate and frame rate, round trip,
  loss, host, assembly, queue and decode times, decoder) with a copy
  button; the status line always shows achieved against requested. The
  lobby leads with your PCs and a Next session summary; connection
  details fold away. The host panel has an Overview and a Settings view,
  a Repair setup button and a Diagnostics fold with a copy-log button.
