The repository had no fuzzing setup despite several natural targets — the CSV parser, the Binance envelope deserializer, and the stateful indicator/aggregator update paths. Add a fuzz/ cargo-fuzz crate (detached from the workspace via its own [workspace] table and the parent's exclude) with four targets: - csv_reader — CandleReader over arbitrary bytes - binance_envelope — RawWsEnvelope deserialization from arbitrary strings - indicator_update — RSI/EMA streaming + batch over arbitrary f64 series - tick_aggregator — TickAggregator over arbitrary tick triples Each target asserts the no-panic contract: malformed input must surface as an Err. fuzz/README.md documents running them (nightly + cargo-fuzz).
