Gitty 0.1.3

Added

• Push and Pull in the commits pane header, on the checked-out branch.
  Push carries the count of unpushed commits (Push 3) and greys out
  when there is nothing to send; on a branch that tracks nothing it publishes
  to origin and sets the upstream. Pull fast-forwards from the upstream
  and greys out when there is none. Git's own output appears above the log,
  clicked away when read — failures stay until dismissed. A push or pull that
  needs a credential prompt fails with git's message instead of hanging (there
  is no terminal behind them); the terminal pane is where it gets finished.
• Every pane hides and comes back: a × at each pane header's end hides it,
  Panes in the title bar lists all four with a dot on the visible ones, and
  Ctrl+1…Ctrl+4 toggle them in layout order. The remaining
  panes share the space; the last visible pane keeps its × hidden, so the
  window is never empty. What is hidden is remembered across restarts, and
  hiding the terminal pane leaves its shells running, scrollback intact.
• The file heading stays in view while scrolling a whole-file diff: when it
  scrolls past the top of the pane it pins itself there until the next file's
  heading pushes it away. A single-file diff is unaffected.
• Every pane goes full screen, not just the diff. ⤢ at the left of each pane
  header fills the window; ⤡, Esc, a header double-click or
  Ctrl+Shift+1…Ctrl+Shift+4 restores the layout. The
  diff's Full Screen / Restore button is gone, its corner button
  replacing it.
• Hovering a pane title shows a styled tooltip spelling the pane's own gestures
  — the keys that hide it and fill the window — with the key labels
  colour-coded.

Fixed

• Reading a long file no longer jumps back to the top when the file changes on
  disk. The position is kept across a reload, with the lines already loaded in
  the source view; only opening a different document rewinds.
• The window list and the dock show Gitty's icon instead of a generic
  placeholder. The desktop entry now carries StartupWMClass=electron: an
  unpackaged Electron app reports electron as its window class (its Wayland
  app_id) whatever app.setName, --class, CHROME_DESKTOP or a renamed
  binary say. Re-run ./setup.sh and restart Gitty to pick it up.
• The work tree pane no longer gets stuck listing changes that are already
  committed. A burst of file-system events could start several refreshes at
  once, and a slow earlier git status landing after a newer one put its stale
  file list back on screen while the diff pane showed the real state. Replies a
  newer refresh has overtaken are now discarded, for the diff pane as well.

Changed
