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

  - Ensure each change provides sufficient test cases to guarantee code correctness
  - Do not arbitrarily modify numbers and constants in test cases, carefully analyze their meaning to ensure test case correctness
  - When writing or modifying tests, check existing test cases to ensure they have scientific naming and rigorous logic testing, if not compliant, modify test cases to ensure scientific and rigorous testing
+ - **Before committing any changes, run `cargo clippy --all-targets --all-features -- -D warnings` to ensure all code passes Clippy checks**
  - After each development completion, first git add . then git commit -m "feat: feature description" or "fix: issue description", ensure compliance with [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/)
  - **Keep commit messages concise and under 72 characters** for the title line, use body for detailed explanations if needed
  - After each development completion, first git push to remote repository
