For example, a\nstring body is `\"Body\":\"test\"` and a nested map is a JSON object. Scalar\nstrings and Base64 bytes receive normal JSON transport quoting; special\nfloats become `\"NaN\"`, `\"Infinity\"`, and `\"-Infinity\"`. JSON-looking\nstrings stay strings, and user map entries named `Type` or `Value`\nremain ordinary data.\n\nLog attributes remain an ordered array of single-attribute objects;\nresource and scope attribute sets become JSON objects. Empty sets are\n`{}`, nil resources remain `null`, and populated scope attributes are\nretained.\n\nUse `json.RawMessage` for the private body field and conversion helper\nso every body is encoded JSON before the record is marshaled. Formatting\nremains local to stdoutlog; shared attribute marshaling and other signal\nexporters are unaffected. Ordinary export errors still reach the caller.\n\nFixes #9127.\nFixes #9128.\n\nSix-sample benchmarks below isolate the `json.RawMessage` refactor\nagainst `deb62de8`, which already emits direct non-OTLP bodies. Scalar\nstrings, bytes, special floats, and empty bodies gain one allocation;\nfinite float and float-array cases use three fewer. Short strings\nmeasured 7.5% slower and escaped strings 16.7% slower; the finite float\nand small-array cases measured 8–11% faster in this run. This is an\nexplicit-type refactor with a performance tradeoff.\n\nBenchmark command: `GOMAXPROCS\u003d2 make\nbenchmark/./exporters/stdout/stdoutlog
