// ISSUE-131: parse_json() returns Message type instead of parsed JSON object
//
// ROOT CAUSE (Five Whys):
// 1. Why does parse_json() return Message? → Not recognized as builtin function
// 2. Why not recognized? → Not registered in builtin_init.rs
// 3. Why not registered? → Only json_parse registered, parse_json alias missing
// 4. Why missing? → Original implementation only registered underscore version
// 5. Why no test? → No validation that both aliases work
//
// FIX: Add parse_json registration to builtin_init.rs (ONE LINE)
//
// EXTREME TDD: RED → GREEN → REFACTOR → VALIDATE
