v0.4.0

Added

• Tabs light up when they need you: a coloured dot in the sidebar or bar,
  or the coloured number in the collapsed sidebar. Green: a command that ran
  10 seconds or longer finished; red: it failed; yellow: a program rang the
  bell or asked for a notification (OSC 9, 777, and 99, which Claude Code
  can send). Looking at the tab clears it. While the window is in the
  background, bunker also shows a desktop notification; clicking it opens
  that tab. Exit codes come from shell integration (OSC 133); without it,
  bunker notices when the shell gets the terminal back. Settings are under
  [notify] and in Preferences > Terminal.

Fixed

• Backspace, Enter, and Tab send their usual bytes to programs that turn on
  the kitty keyboard protocol's basic mode, as the protocol says; only
  programs that ask for every key as an escape code get escape codes for
  them. Backspace sent an escape code before, which some programs did not
  take as Backspace, and a shell left behind by a program that crashed with
  the mode on lost Enter.
• bunker config set created no file when the config did not exist yet and
  the value equalled the default.
