v0.2.5

Added

• Take over an agent you started outside muxel — a project's right-click menu has
  Import…, which looks for agents running, or last run, outside muxel and lists
  what that project can take over. A tmux session is the best case: muxel attaches a
  pane to it, the agent keeps running exactly as it was, and the pane survives a
  restart — that works whatever is inside, including agents that cannot resume a
  conversation at all. An agent running outside tmux cannot have its terminal taken
  over, so muxel offers to resume its conversation in a new pane instead and says so
  in the row, because the one you started keeps running on it too. A past
  conversation with nothing on it simply reopens where it left off. Each row says
  what that agent was working on, which is what tells two sessions in the same folder
  apart, and anything a pane already holds is left out, so importing can never put
  two panes on one agent. Sessions elsewhere on the machine are listed as well,
  tagged as outside the project, so you can pull one in on purpose. Remote projects
  are searched over the connection they already have.
• muxel installs on NixOS — nix run github:ProjectHax/muxel runs it,
  nix profile install keeps it, and a NixOS or home-manager configuration can pull
  it in through the flake's overlay. There is a development shell too, which is what
  lets a checkout build there at all: nothing on NixOS puts the Wayland, Vulkan,
  fontconfig and WebKit pieces where a build expects to find them. Linux, x86_64 and
  aarch64.
• muxel offers to install tmux when it is missing — without tmux, local agents
  still run but do not survive closing muxel, and nothing said why. The first launch
  that finds tmux missing now offers to install it and shows the exact commands
  before anything runs. Only the install itself is elevated, through the desktop's
  own password dialog; on a Mac it uses Homebrew as you, and a Mac without Homebrew
  is pointed at it. The package manager's output streams into the dialog, which can
  be hidden while it works, and a failure shows what went wrong along with a command
  to paste into a terminal yourself. The offer is made once, and Install tmux…
  in Settings opens it again.

Fixed

• A conversation Claude moved still resumes — Claude can carry a conversation
  into another project directory when its working directory changes, or when you
  pick a conversation belonging to somewhere else. muxel only ever looked where the
  pane had started, decided the conversation had been deleted, and opened the pane
  blank on a new one. It now finds a conversation by its own id wherever it has
  moved to, and starts Claude in the directory Claude recorded for it — which
  matters, because Claude refuses to resume a conversation from anywhere else. A
  conversation is given up on only once muxel has confirmed it is really gone: a
  session store it could not read leaves the pane's conversation alone rather than
  quietly replacing it.
• Reading a pane can no longer take every local agent down with it — finding an
  agent's last reply, for read-aloud or for an outside tool driving muxel, asked tmux
  for the pane's scrollback. On some tmux builds that request crashes the tmux
  server, and one server holds every local session, so a single read killed every
  agent at once — and with something reading repeatedly, agents were relaunched and
  killed again before any of them could finish starting. muxel now reads a pane from
  its own terminal, which keeps far more than any of those callers ask for, so tmux
  is not asked at all. Remote panes have always worked this way.
• The Linux .deb installs on the current Ubuntu and Debian — it asked for
  library names that both distributions have since retired, so it refused to install
  on Ubuntu 24.04 and Debian 13 while working fine on older releases. It now names
  the current and the previous names together, so one package installs on all of
  them. The .rpm was never affected.
