🤖 Augment PR Summary

Summary: Increases the default maximum HTTP request body size to 4 MB to better support realistic JSON Schema evaluate/trace payloads.

Changes:

• Raise HTTPRequest::body() default max_size to 4 * 1024 * 1024 bytes and document 413 mapping.
• Clarify 413 error messaging for JSON Schema evaluate/trace (REST) and MCP (JSON-RPC) paths.
• Update the public API error schema’s payload-too-large detail constant to match the new message.
• Document the 4 MB cap in docs/api.md for evaluate and trace endpoints.
• Adjust e2e resource-size assertions to reflect the updated schema content.

Technical Notes: The 413 response is aligned with RFC 9110 §15.5.14 (“Content Too Large”).
