Add 'ask edit' subcommand and collapse multi-line task descriptions

- ask edit opens $EDITOR and creates a task from the (multi-line) content,
  reusing the shared internal/editor package
- collapse newlines in list output and fish completion so multi-line
  descriptions render on one line and don't break completion

Bump version to 0.40.0
