Packaging was silently hanging forever because yauzl 2.10.0 read streams
emit no data events under Node 26, causing extract-zip to block indefinitely
inside @electron/packager 20. Fix: postinstall script patches
@electron/packager/dist/unzip.js to use bsdtar (libarchive) instead.
bsdtar was chosen over 7z because 7z refuses chained symlinks in macOS
.app framework bundles. Both package:linux and package:mac now produce
correct output.
Also corrects the V3 API bootstrap contract in api_client.ts:
- SearchQuery body was wrapped in an extra {search_query: ...} layer — removed
- x-no-account-id header standardised to 'bypass'
- Redundant x-no-account-id removed from file download headers
- Smoke test rewritten to validate the real two-step bootstrap path
