The Mac App Store build's first-run folder picker ran through AWT, which
claims NSApp before Tao installs its event loop — the app then runs on
with no window and no crash. Move the picker and its alerts into the
Objective-C helper so nothing touches AWT before nucleusApplication().
Localized dialog text now comes from SandboxStrings, which reads the
packaged Compose Resources .cvr value files directly; getString() can't
be called pre-Compose because resolving a ResourceEnvironment
initializes AWT for the density qualifier. Value files layer English
under each locale so a key Crowdin hasn't round-tripped falls back to
real text rather than its own name. SandboxStringsTest guards the format
coupling, since a Compose upgrade would otherwise only surface as raw key
names on an App Store first launch.
Also declare the clang flags as an input on compileMacosBookmarksLib so a
flags-only edit can't leave a stale dylib for signMacAppResources to sign
into the bundle, and document the sandboxed config and data paths in
SUPPORT.md.
The #import/#include directives were split across two lines, which clang
rejects, breaking the compileMacosBookmarksLib task for App Store builds.
