Subject: [PATCH] chore(dash-spv): forbid `std::sync::Mutex` / `RwLock` via
 clippy
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds a `clippy.toml` with `disallowed-types` for `std::sync::Mutex`
and `std::sync::RwLock` so callers are nudged toward the
tokio equivalents (the crate is async/tokio throughout — a blocking
lock can stall the runtime).
