def self.find_task_file
  dir = Dir.pwd
  loop do
    candidate = File.join(dir, ".loki")
    return candidate if File.exist?(candidate)
    parent = File.dirname(dir)
    break if parent == dir
    dir = parent
  end
  nil
end

.load_loki(dir) ⇒ Object

Load all *.loki files from dir in alphabetical order. Each file typically reopens class Tasks to add recipes. The .loki entry point is excluded — it is loaded separately by run!.
