Walks priv/templates/mob.new/ios/**/*.eex (resolved from mob_new —
see MobDev.Adopt.Generator), renders each, and writes via
Igniter.create_new_file/4 with on_exists: :skip. Then copies binary
static iOS assets via direct File.copy!/2.
Idempotent — on_exists: :skip for EEx-rendered files; File.exists?
pre-check for binaries.
With --python, also applies the Pythonx wiring ({:pythonx, ...} dep
in mix.exs, generates lib/<app>/python_paths.ex). iOS-only — Android
Python is intentionally out of scope. Mirrors mix mob.enable pythonx.
