Research direction

Research how Go implements `go doc` and explore the Gleam compiler's source, particularly the CLI entry point (e.g., `src/cli.rs`) and any existing documentation generation code. Look for how doc comments are parsed (e.g., in `src/ast.rs` or `src/format.rs`). Propose a new `gleam doc <module>` command that extracts and displays documentation in the terminal. Consider formatting output similar to Go's style.
