Summary

Part 5 of 6 for Linux desktop support (stacked on #42 / linux-4-media, #41 / linux-3-input, and #38 / linux-2-basics).

Adds Linux phone storage synchronization and file manager bookmark integration:

• Linux Storage Synchronization (desktop/app/src/linux/storage.rs):
  • Synchronizes paired phone storage under ~/Nectarlink/<Phone name> when the phone's storage toggle is enabled.
  • Streams remote files into atomic .nectarlink-part temporary files (O_NOFOLLOW, 0o600) before renaming into place, preserving remote modification timestamps.
  • Detects user additions and edits in the local folder and pushes them back to the phone via storage.mkdir and storage.write.
  • Automatically registers and cleans up ~/.config/gtk-3.0/bookmarks entries (file://<encoded_path> <DeviceName> (NectarLink)) so paired phones appear in GTK/GNOME/XFCE/Cinnamon file managers.
• Cross-Platform Storage Dispatch (desktop/app/src/storage.rs, desktop/app/src/core_host.rs):
  • Routes storage::{start, sync, on_event, shutdown, unregister_all, sync_root_path_for, open_in_explorer} to linux::storage on Linux.
  • Advertises STORAGE_MOUNT, STORAGE_READ, and STORAGE_WRITE capabilities on Linux.

Verification

• cargo fmt --all --check
• cargo xtask strings --check
• cargo clippy --locked -p nectarlink-desktop -p nectarlink-vcam -p s1-qt-rust --all-targets -- -D warnings
• cargo test --locked -p nectarlink-desktop -p nectarlink-vcam (306 + 6 unit tests pass)

Thanks for opening this. Our notes for this part are on #38 (comment). The main thought, only a suggestion: syncing walks the phone every 4 s and copies every file into ~/Nectarlink/<phone>, which can mean gigabytes the user didn't ask for, and a file deleted locally comes back on the next pass. An on-demand mount (FUSE) reads only what's opened. We tried one against the kernel protocol, and it held up end to end, including a 1 GiB read and recovery after a crash; it's on linux-review-fixes if it helps (b346bfe, ea1f8e0, e58ee10). KDE's sidebar also reads ~/.local/share/user-places.xbel besides GTK's bookmarks.

Updated with linux-4-media and integrated @thtbee's Part 5 review fixes from linux-review-fixes (64d36fc — on-demand FUSE directory/file fetching via StorageListing::request and StorageDownload::fetch, ENOENT negative caching, and fusermount3 -u -z teardown). Huge thanks @thtbee for the collaborative effort!

Reviewed on the final branch (0b37495) along with the rest of the series: all findings addressed, and Linux and Windows checks, the FUSE end-to-end run and the package builds pass. Thank you.
