77dc466 chore: update rand 0.9.2 -> 0.9.3 (Vadim Anufriev) Pull request description: Fixes bitcoindevkit#269 Update transitive dependency `rand` from 0.9.2 to 0.9.3 via `cargo update -p rand@0.9.2` to resolve RUSTSEC-2026-0097. Note: bitcoindevkit#268 (`rand 0.8.5` via `secp256k1` and others) remains unaffected by this change and needs to be fixed upstream. ### Checklists #### All Submissions: * [x] I've signed all my commits * [x] I followed the [contribution guidelines](https://github.com/bitcoindevkit/bdk-cli/blob/master/CONTRIBUTING.md) * [x] I ran `cargo fmt` and `cargo clippy` before committing Top commit has no ACKs.
