Fix List.get with method syntax causing cycle in layout computation 
When calling List.get with method syntax (my_list.get(0)), the
interpreter was causing a cycle in layout computation because rigid
type variables weren't being properly resolved.

The fix unifies the method's first parameter type with a copy of the
receiver type before instantiation. This properly resolves rigid type
variables (like `item` in List.get) to concrete types. A copy of the
receiver type is created before unification to avoid corrupting the
original type, since unification modifies both sides.

This is the same approach used for no-args method dispatch (like
List.first), but with the additional copy step needed because the
multi-args path may reuse types across multiple method invocations.

Fixes #8662

CLI

This directory contains the source code for the roc command-line interface (CLI) tool.

The CLI is the main entry point for developers using Roc. Its responsibilities include:

  • Command Parsing: Parsing commands (e.g., build, run, fmt, test) and their options through cli_args.zig
  • Compilation Orchestration: Managing the compilation pipeline and integrating with the Roc compiler
  • Linker Integration: Using an abstraction for the LLD linker as a library through linker.zig for code generation
  • Performance Profiling: Integration with Tracy profiler for performance analysis
  • Testing & Benchmarking: Built-in testing and benchmarking capabilities through bench.zig
  • Shared Memory Management: Testing utilities for the shared memory system used in IPC

The CLI coordinates between the compiler frontend (parsing, type checking) and backend (code generation, linking) to provide a seamless development experience.
