v0.12.0

Added

• Each account shows the plan its login says it is on, such as Max 20x, Team 5x or
  Pro for Claude Code and Plus or Pro for Codex. The window shows it as a tag beside
  the account's name, the menu after the name, as in work · Team 5x, and VoiceOver
  says it after the name. pitboard shows it in a dim column after the address, there
  only when some account has a plan. pitboard --json gives it as plan, null where no
  login Pitboard read for the account said one. Pitboard records the plan on the account
  when it enrols it and each time a read sees its login, so a read that asks nothing, such
  as pitboard status --offline, shows it too. A read sends nothing more anywhere to learn
  it: Claude Code's login keeps subscriptionType and rateLimitTier, and Codex's ID
  token keeps chatgpt_plan_type.
• An install script puts the command line on macOS and Linux without Homebrew or Rust:
  curl -fsSL https://usepitboard.com/install.sh | sh. It downloads the release's tarball
  for the machine, checks it against the SHA-256 written into the script when the release
  was made, and installs pitboard in ~/.local/bin, with its man page and completions
  under ~/.local/share. PITBOARD_INSTALL_DIR names another folder, and the share
  folder beside it takes the rest. It edits no shell profile: when the folder is not on
  PATH, it prints the command that puts it there. Run it again to update. It refuses to
  run as root or under sudo, where Pitboard changes nothing. Each release carries its own
  copy, attested like its other files, at
  https://github.com/datlechin/pitboard/releases/download/v<version>/install.sh.
