Objective

Implement parse_json_map, a strict parser for a tiny JSON-like data format.

Steps

• Create json_map_parser.c and json_map_parser.h.
• Use the json_node and json_pair structures from the starter header.
• Expose int parse_json_map(json_node *dst, FILE *stream);.
• Return 1 when parsing succeeds and -1 when parsing fails.
• Support integer numbers, including negative numbers written with - followed by one or more digits.
• Maps use {} and comma-separated "key":value entries.
• Store map entries in the same order as they appear in the input.
• Strings may escape only \\ and ".
• Whitespace is not ignored; any space, tab, or newline in the input is invalid.
• On an unexpected byte, print Invalid token '<char>' followed by a newline.
• On unexpected end of file, print Unexpected end followed by a newline.
• Allocate all strings, pairs, and child nodes needed by the parsed tree.
