Subject: [PATCH] fix(deps): pin redis to 0.27 (MSRV 1.70, works with 1.85
 toolchain)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

redis 1.3.0 requires Rust 1.88, conflicting with the workspace MSRV of
1.85 (rust-toolchain.toml). redis 0.27.6 has MSRV 1.70, well within
1.85. The xadd_maxlen + StreamMaxlen::Approx API is identical between
0.27 and 1.3 — no kimi-worker T8 code changes needed beyond the version
pin. BSD-3-Clause license unchanged.
