v0.2.0

Changed

• Renamed to Ta-Da. The binary is now tada, environment variables are
  TADA_*, config lives in ~/.config/tada/tada.json, tadarc, .tada/ and
  TADA.md. The repository moved to
  ItsCetla/tada and the site to
  tada.cetla.dev.
• On first run, settings and data from ~/.config/crush and
  ~/.local/share/crush are copied into the new Ta-Da folders, and CRUSH_*
  environment variables are still honoured. Project .crush/ session history
  is not moved; .crush/skills and .crushignore are still read.
• New "cetla" default theme, Ta-Da wordmark and a short startup intro
  (skip with any key; turn off with TADA_NO_INTRO=1 or
  options.tui.intro: false).

Added

• tada update (--check, -y): downloads the latest release from GitHub,
  checks it against SHA256SUMS.txt and replaces the binary.
• Background update check: at most every 6 hours, asks api.github.com for the
  latest release and tells you once per new version. Never downloads on its
  own. Turn it off with options.update_check: false,
  option update-check false or TADA_NO_UPDATE_CHECK=1.
• Windows installer (tada_<version>_Windows_<arch>_Setup.exe): per-user
  install without admin rights, adds tada to PATH, Start menu entry,
  uninstaller in Settings → Apps. Upgrading from the 0.1.0 Crush installer
  removes the old crush.exe and shortcuts.
