Requested by Ben in a daily maintenance routine.

Before: Cargo.lock pinned chacha20 0.10.0, which was yanked from crates.io on 2026-08-27. cargo audit flags it as a yanked crate, and it is compiled into the runtime binary via rand 0.10 (used by actix-http, tracing-batteries and bender itself).

After: chacha20 is at 0.10.2. That release fixes the SSE2 backend of the ChaCha RNG using an SSE4.1 intrinsic (RustCrypto/stream-ciphers#580), which could fault with an illegal instruction on CPUs without SSE4.1. cargo audit no longer reports it as yanked.

How: cargo update -p chacha20 --precise 0.10.2. This changes only the lockfile, with no manifest or code changes. I ran cargo test --locked --all-features --no-fail-fast locally and it passed.

Moves chacha20 from the yanked 0.10.0 release to 0.10.2.
chacha20 0.10.2 fixes the SSE2 backend of the ChaCha RNG using an
SSE4.1 intrinsic, which rand's StdRng/ThreadRng exercises at runtime.
Lockfile-only change.
