Code Review

This pull request adds a comprehensive development guide for the Apache Beam YAML SDK, detailing the project structure, environment setup, and testing procedures. Review feedback correctly identified a technical inaccuracy regarding the implementation of IO transforms and recommended clarifying the installation command to use repository-relative paths.

- `standard_io.yaml` - Declarations of standard IO transforms and their mappings to providers.
- `standard_providers.yaml` - Configuration for standard providers (e.g., Java expansion services).
- `yaml_combine.py` - Implementations for aggregation and combining operations.
- `yaml_io.py` - Python implementations for builtin IOs (PubSub, BigQuery, Iceberg, etc.).

The description of yaml_io.py as containing "Python implementations" for IOs like Iceberg is inaccurate. Iceberg is implemented in Java and accessed via cross-language providers. yaml_io.py primarily contains the logic for the IO provider and mappings to various implementations.

Suggested change
- `yaml_io.py` - Python implementations for builtin IOs (PubSub, BigQuery, Iceberg, etc.).
- yaml_io.py - Mappings and logic for IO transforms (e.g., PubSub, BigQuery, Iceberg).

- `yaml_transform.py` - Core YAML expansion logic, parsing, and translation to Beam pipelines.

## Environment Setup
Since Beam YAML is implemented within the Python SDK, the environment setup is identical to Python development. Refer to the `python-development` skill for details on using `pyenv` and installing in editable mode (`pip install -e .[gcp,test]`).

The pip install command should be executed from the sdks/python directory for the relative path . to be correct. Since the rest of this guide uses paths relative to the repository root, it is clearer to provide the command that works from the root.
