| The initializer for module `A.B` is called `initialize_A_B` and will automatically initialize any imported modules. | |||
| Module initializers are idempotent (when run with the same `builtin` flag), but not thread-safe. | |||

| **Important for process-related functionality**: If your application needs to use process-related functions from libuv, you must call `lean_setup_libuv(argc, argv)` before calling `lean_initialize()` or `lean_initialize_runtime_module()`. This ensures that libuv's process handling capabilities are properly configured with the command-line arguments, which is essential for certain system-level operations that Lean's runtime may depend on. | |||

This needs to mention that users should replace their argv with the one returned by lean_setup_libuv.

This PR adds a function called
lean_setup_libuvthat initializes required LIBUV components. It needs to be outside oflean_initialize_runtime_modulebecause it requiresargvandargcto work correctly.
