v0.1.2 - Better scrolling and status

Terminal viewport and tab chrome after v0.1.1.

• History stays where you left it. Scrolling up no longer follows new
  output. The live tip is the last screen of the buffer, not past it, so a
  new attach is not a blank pane. A dropped connection keeps that last view
  on screen (dimmed) while it retries.
• Tabs. Hover lightens a chip without changing the strip height. Color
  still tracks connected, connecting, and failed.
• Status. The focused pane's size sits next to Exit. A copy notice
  replaces the hint for a moment. Idle polls do not wake the GUI unless the
  screen changed.

Prebuilt Linux, macOS, and Windows artifacts are attached below. Linux and
Windows builds are unsigned; macOS builds are ad-hoc codesigned, not notarized.

Known limitations: MFA, host and user certificates, ProxyJump, ProxyCommand,
sk-ecdsa and file-based SK keys, and reusing one SSH connection across tabs
are not supported. Remote hosts are Linux with stock OpenSSH and tmux. No
performance baselines are published yet.

v0.1.1 - Better SSH

Identities, hardware keys, install, and the terminal workspace after v0.1.0.

• Identities, then the agent. Files from the profile (or OpenSSH's default
  id_ed25519 / id_ecdsa / id_rsa when none are set) are offered in order,
  then the local agent unless IdentitiesOnly is set. There is no
  agent-versus-key radio. A missing User is the local account. HostKeyAlias
  is the known-hosts lookup name; TCP still uses HostName. Encrypted files and
  unsupported agent algorithms are named in the error (the SSH agent holds 3 keys, 1 unsupported (sk-ecdsa-…)).
• Agent-held sk-ssh-ed25519. Hardware keys in the local agent are offered;
  signing stays in the authenticator. sk-ecdsa and file-based SK keys are not.
• Saved workspace. Restored tabs re-read identity policy and blockers from
  ~/.ssh/config. An unreadable workspace.conf is a system dialog before the
  window opens: clear the file, or exit and leave it.
• Desktop. Maximize is tmux zoom and keeps focus. Exit returns to the form
  and retitles the tab from those fields. Alternate-screen panes and a History
  setting below tmux's buffer are not warned as lost output. After keys or
  wheel, remote echo runs at 20 fps for a short time. Wheel ticks are one per
  40 points; leftover smoothing cannot add extra ticks.
• Install. make install does not assume GNU install -D. On macOS it
  writes ~/Applications/Starcom.app. macOS/Windows icons use a full PNG
  family for cargo-bundle --bin.

v0.1.0 - First working version

First release. Starcom attaches to existing remote tmux sessions over its own
embedded SSH client and draws them in a native window.

• Attach, don't replace. Uses tmux control mode (tmux -N -C) against a
  stock remote tmux. Starcom never starts a tmux server implicitly, never
  modifies global tmux settings, and leaves the ordinary tmux client usable
  as a fallback. Closing a tab or the window detaches; remote jobs keep running.
• Embedded SSH. Sunset plus RustCrypto — no OpenSSL, libssh2, ring, AWS-LC,
  or ssh subprocess. Strict known-hosts verification with exact,
  port-qualified, and hashed entries; unknown or changed keys always fail.
  Ed25519, RSA/SHA-256, and ECDSA P-256 keys, and Unix and Windows OpenSSH
  agents. Hardware-backed sk-* keys are not offered.
• ~/.ssh/config reading, without executing anything. Host patterns,
  HostName, User, Port, IdentityFile, IdentitiesOnly,
  UserKnownHostsFile, and bounded Include. Directives that cannot be
  honoured exactly are shown as blockers rather than bypassed. Multiple
  IdentityFile entries are a blocker in this release.
• Authentication. The form chooses an SSH agent or a key file. Encrypted
  files need ssh-add.
• Automatic reconnection, for transport loss only. Authentication,
  host-key, missing-session, server-exit, and detach failures stop and wait.
  Nothing typed while offline is queued, and no uncertain input is replayed.
  A sleeping laptop or a black-holed control stream is treated as transport
  loss, not as a protocol fault.
• Session discovery and creation. Listing uses tmux -N and cannot bring a
  server into existence. Creating a session is only reachable from an explicit
  confirmation.
• Saved tabs. Destinations and preferences persist; credentials, host-key
  material, and terminal contents never do. Restoring a workspace opens forms,
  not connections.
• Desktop client. Blade/egui rendering of Alacritty's terminal model, panes
  and tabs, mouse selection, scrollback, paste confirmation, and draggable pane
  dividers. Remote resizing is opt-in.
