Migrate from legacy winapi crate to official windows crate

[fasuizu-br]

Description

The project uses winapi = "0.3" for Windows API bindings. The winapi crate is no longer actively maintained — the Rust Windows ecosystem has migrated to the official windows crate maintained by Microsoft.

Other projects in the risoflora organization (e.g., system_shutdown) have already migrated to windows = "0.62".

Current

[target.'cfg(windows)'.dependencies]
winapi = { version = "0.3", features = ["winuser"] }

Suggested migration

[target.'cfg(windows)'.dependencies]
windows = { version = "0.62", features = ["Win32_UI_Input_KeyboardAndMouse"] }

The API calls (SendInput, GetKeyState, etc.) have direct equivalents in the windows crate with improved type safety.

Benefits

• Active maintenance and security updates from Microsoft
• Better type safety (HRESULT handling, strong types)
• Consistent with the rest of the risoflora ecosystem
