The 1,375-line library/commands.rs hosted only unregistered Tauri
commands (54 of them) plus a path-compat pub use of state types.
Every #[tauri::command] in the file is V2-replaced and uncalled.
The state-types pub use was the only external surface and is
already exported canonically from library/mod.rs.
- Delete src-tauri/src/library/commands.rs entirely
- Drop pub mod commands; from library/mod.rs
- Update session_lifecycle.rs to use crate::library::LibraryState
(the canonical path) instead of crate::library::commands::LibraryState
- Refresh the doc comment in library/state.rs to reflect the
post-cleanup layout
