v3.39.1

Fixed

• Detach on an attached remote workspace now works. Right-clicking the
  sidebar row opened its menu, but pressing "Detach" did nothing at all. The
  menu dismissed itself on mousedown, which arrives before click, so the
  button unmounted under the pointer before its own handler could ever run —
  the action was unreachable rather than broken.

• Mirrored remote panes use your terminal font, theme and contrast floor.
  An attached remote workspace built its terminal without any of the app's
  visual settings, so it fell back to xterm's own defaults — monospace at
  15px on black, outside the theme's ANSI palette. Next to a local pane it read
  as slightly bolder and slightly larger, because it was. Changing the settings
  now updates the mirror without dropping what the remote has already sent.

  One difference remains: local panes render through WebGL and mirrors use
  xterm's DOM renderer, whose text antialiasing differs. Matching size, family
  and palette removes most of the mismatch, not all of it.

• Mirrored panes no longer tear on Korean and other wide text. The mirror
  re-renders a grid the remote daemon computed, but it was the one terminal in
  the app that skipped the shared Unicode width model — so every double-width
  character put the two grids one cell further apart, and rows arrived
  interleaved and torn.

• Mirrored panes stay inside their box. A remote pane with more rows than
  the local cell can show rendered taller than its container, and nothing in
  the chain clipped it, so terminal output painted over the composer bar and
  the sidebar. Typing made it obvious because that is when the overflowing rows
  got repainted.

  This clips rather than scales: geometry belongs to the remote daemon and the
  mirror never resizes it, so a remote grid taller than the local cell now has
  its lower rows cut off instead of drawn over the app. That is the better of
  two bad outcomes, not a good one — the cropped region is where the cursor and
  live output are. Fitting the mirror to the cell needs a geometry negotiation
  that does not exist yet.
