Technical Exegesis...
Reads an integer value from a JSON object by key. Takes json string and key string. Calls FindKeyPosition helper to search for "\"key\":" pattern. FindKeyPosition returns position after colon, skipping whitespace. If key not found, returns 0. If found, calls atoi to parse integer from json+pos. Returns integer value, or 0 if key not found.
This function deserializes integer from JSON string. FindKeyPosition searches for exact key match with quotes.

This function deserializes integer from JSON string. FindKeyPosition searches for exact key match with quotes. atoi parses numeric characters until non-digit encountered. Returns 0 for missing keys (ambiguous - could be actual zero value). Use for reading integer properties from JSON documents. Common pattern: score = jsonReadInt(json, "score"), lives = jsonReadInt(json, "lives"). Pair with jsonWriteInt for round-trip serialization. Handles negative numbers. Stops parsing at first non-numeric character.
