Export and Import were a link to the server and a reject("needs a server") on the
desktop. Both now run in the core with no server:
- core/src/local/portable.rs builds the same zip the server writes (notes.json,
a Markdown file per note, each attachment this device holds) and reads either
export marker or a Google Keep Takeout zip, with the server's decompression
budget and an all-or-nothing transaction. Export saves to Downloads (no new
plugin) and the sidebar says where; Import takes the archive as raw IPC bytes.
- core/testdata/portable.json pins the format for both copies: the server runs
its Keep and native readers against it (test_portable_fixture.py) and checks
its real export's keys (test_integration.py); the core runs the same cases.
- Found on the way: both importers skipped a Keep note that is only a photo as
"empty". It now imports, on the server and in the core.
- New dependency, approved: `zip` (deflate only) plus `flate2` on its pure-Rust
backend, both already in the lockfile.
The AppImage applications-menu toggle moves from Account, which the desktop
never shows, to the Sync page; the first-run prompt now says so.
errorMessage (#5236) replaces the hand-rolled `.error ?? …` / `.message ?? e`
reads at the remaining catch sites, so a desktop failure shows its real reason.
Task #5170.
