Subject: [PATCH 1/2] fix: downgrade to edition 2021 and MSRV 1.82 for stable
 Rust compatibility
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Edition 2024 requires Rust 1.85+ which breaks installation for users
on stable toolchains (e.g., Rust 1.84). MSRV 1.82 matches cachekit-core
dependency requirements.

Changes:
- rust/Cargo.toml: edition 2024 → 2021, rust-version 1.91 → 1.82

Fixes #30
