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).

//! Fuzz indicator updates with arbitrary `f64` sequences.

//!
|
|
//! Every indicator must tolerate any finite-or-not input stream — NaN, ±inf,
|
|
//! subnormals, abrupt jumps — without panicking, and `batch` must agree with
|
|
//! the streaming `update` path.
