v1.5.1

Fixed

• Keep live settings in one place, ~/.redesign/config/, whether the app is packaged or run
  from source. Running from source pointed at src/config/ itself, so saving a prompt, adding a
  model, or building a Prompt Builder combination wrote user data into files that are tracked in
  git and compiled into the shipped binary as seeds: a working copy went dirty on ordinary use,
  and a stray commit would have published private presets. Those files are now seeds only, and
  the test suite runs against them in an isolated home so a developer's own settings cannot
  change the result of a test run.
