refactor: extract psysonic-syncfs crate (M4/7)
Moves all on-disk cache + device-sync code out of the top crate:
crates/psysonic-syncfs/ new lib crate
src/cache/{offline,hot,downloads,fs_utils} unchanged behaviour
src/sync/{batch,device} (no tray.rs — that's UI)
src/file_transfer.rs shared HTTP helpers
src/lib.rs + DownloadSemaphore type
+ sync_cancel_flags fn
The shell crate keeps `lib_commands/sync/tray.rs` (OS tray icon — UI
concern, will move to shell-tauri at M7) but drops the rest of
`lib_commands/cache/` and the syncfs sibling files.
Tauri command quirk surfaced and resolved: `#[tauri::command]` puts its
`__cmd__*` and `__tauri_command_name_*` helper macros at the *exact*
module of the function, and `pub use` doesn't carry them across module
boundaries. invoke_handler! in lib.rs now references each syncfs
command via its full deepest path
(`psysonic_syncfs::cache::offline::download_track_offline`, etc.) so
Tauri's macros resolve at the right scope. Same approach the audio
crate already uses (`audio::commands::audio_play`).
Cross-crate ref migrations applied via batch sed:
crate::audio::* → psysonic_audio::*
crate::analysis_runtime::* → psysonic_analysis::analysis_runtime::*
crate::analysis_cache::* → psysonic_analysis::analysis_cache::*
crate::subsonic_wire_user_agent → psysonic_core::user_agent::*
super::super::file_transfer:: → crate::file_transfer::
Behaviour preserving. Cargo check + clippy --workspace clean.
