fix: add serial_test annotations and fix borrowing in tests

- Add #[serial_test::serial] to kiln-foundation tests that share global
  memory budget state (bounded_deque, all_available, memory_operation,
  size_calculation, hashmap, safety_monitor)
- Fix pass-by-value to pass-by-reference in kiln-wasi extract_length tests
- Simplify kiln-decoder test assertions
- Add serial_test dev-dependency to Cargo.lock
