fix: resolve all Clippy warnings across codebase - Fixed field reassignment warnings in ecstore/src/file_meta.rs by using struct initialization instead of default + field assignment - Fixed overly complex boolean expression in ecstore/src/utils/os/mod.rs by removing meaningless assertion - Replaced manual Default implementation with derive in crates/zip/src/lib.rs - Updated io::Error usage to use io::Error::other() instead of deprecated pattern - Removed useless assertions and clone-on-copy warnings - Fixed unwrap usage by replacing with expect() providing meaningful error messages - Fixed useless vec usage by using array repeat instead - All code now passes comprehensive Clippy check with --all-targets --all-features -- -D warnings
