feat: add signal handling for graceful shutdown on Windows and Unix (#5023)

* feat: add signal handling for graceful shutdown on Windows and Unix

Co-authored-by: oomeow <oomeow@outlook.com>

* chore: update Cargo.lock

* fix(windows): restore shutdown hook build by enabling missing Win32 APIs and removing stray tracing call

Includes the required windows-sys feature expansions and replaces a leftover tracing reference so the Windows shutdown hook builds successfully.

* fix: add deprecation warnings for encrypt_data and decrypt_data functions
