fix(dead-code): exclude annotated Tauri commands (#1543) (#2019)

Browse Source 
Rust command attributes were not retained as decorators, so runtime entry points could appear as dead code.
Preserve tauri::command metadata in both native and fallback extraction and reuse the existing decorated exclusion.
Add SQLite regression coverage and native/fallback parity checks, including negative cases.
