Problem: - cargo-watch v8.5.3 requires Rust edition2024 which is not stable yet - Even Rust 1.83 doesn't support edition2024 - Build fails with: feature 'edition2024' is required Solution: - Pin cargo-watch to version 8.4.0 - This version works perfectly with stable Rust 1.83 - No functional difference for development purposes Change: RUN cargo install cargo-watch → RUN cargo install cargo-watch --version 8.4.0
