mix precompiled.deps (precompiled v0.2.1)

Installs signed precompiled builds of the dependencies Mix is about to compile, and rechecks the ones installed earlier. Not meant to be run by hand: add it to the project's deps.loadpaths alias, which every mix compile, test, run and release passes through before Mix compiles the dependencies:

def project do
  [
    ...,
    aliases: [
      "deps.loadpaths": ["deps.compile precompiled", "precompiled.deps", "deps.loadpaths"]
    ]
  ]
end

The first entry compiles this library so the task exists; without it Mix would compile every dependency first. In an umbrella the alias goes in the root mix.exs. Does nothing without config :precompiled, source: ... or PRECOMPILED_SOURCE. mix igniter.install precompiled writes the alias and the config (Elixir 1.18+, not in an umbrella).

mix do clean --deps + compile installs twice: clean loads paths first, which runs the alias once before it deletes _build, and the compile after it installs again. The result is correct, just one install slower.
