A browser or CDN holding an assets/app.js from before the shell's element
IDs were renamed runs it against the newer index.php, where it grabs
btn-logout/btn-rescan/nav-user/nav-username/app — all now null — and throws
before it can unhide #app-shell. The result is a blank page whose only clue
is a TypeError in the console.
- index.php: asset() stamps local css/js with the file mtime, so a deploy is
a new URL and a stale copy can't be paired with a newer shell.
- index.php: install an error handler ahead of every other script (capture
phase, so failed resource loads are caught too) that paints uncaught
errors, rejections and load failures into a #boot-error panel. It works
even when app.js itself is what failed, which is this case.
- includes/db.php: add a register_shutdown_function fatal handler, since
set_exception_handler never sees parse errors, exhausted memory or a
failed require — those were ending requests with an empty body. Both
handlers flush partial output and answer in JSON; display_errors stays off
so a warning can't corrupt a JSON body.
- New optional DEBUG config flag adds exception type, file:line and trace to
those responses. config.php is gitignored, so installs without the setting
default to false.

registerUser() declared `: string|true`; the bare `true` type requires
PHP 8.2, so including auth.php was a fatal error on PHP 8.0/8.1 — every
login/API call returned 500 while install.php (which doesn't include
auth.php) worked. Use string|bool instead. Also install a JSON exception
handler so future server errors surface a message to the SPA instead of
a blank 500.
