bsv-wallet-cli 0.7.3

//! P0-1c (bsv-stack-lean #48): the header source that checks every merkle
//! root is the operator's own choice, never a third party's by default.
//! The CLI resolved an unset `CHAINTRACKS_URL` to the public Babbage
//! chaintracks, behind which the toolbox asked WhatsOnChain
//! (`[SRC] bsv-wallet-cli@f21fc37 src/services_env.rs:27-54`). Our own header
//! service, `chaintracks-cloudflare`, documents no public URL (its
//! `wrangler.toml` and README name none), so the setting is required.
//!
//! One test in its own process: it sets the environment.
