Mosaic 0.1.3

[0.1.3] - 2026-05-12

Added

• Pane drag & rearrange — grab a pane by its header and drag it to
  reorganize the workspace layout. Drop targets split or swap panes within the
  tile tree, so you can recompose a workspace without tearing it down.

Changed

• Shell panes now ignore the double-Ctrl-C "close pane" shortcut. Both
  Ctrl-Cs are forwarded to the running process, so hammering Ctrl-C kills a
  stubborn command instead of closing the pane. Provider/agent sessions still
  close on a double Ctrl-C.
• Vendored libghostty: the Last login: … banner is now always suppressed
  when a new shell pane starts.

Fixed

• Control-key combinations in shell panes are now encoded the way Ghostty's
  native macOS app does: Ctrl-C reaches the shell as SIGINT, and other
  control sequences (Ctrl-D, Ctrl-Z, Ctrl-\, …) behave correctly. The
  key event is built with the right consumed_mods, text payload, and
  unshifted codepoint instead of the previous private-use-area filter.
• The session-count badge on each workspace in the rail no longer counts
  archived sessions — those live under the Sessions panel's "Archived"
  section.
