fix(android): say why libcraft.so did not load, instead of nothing at all

The load was a bare try/catch returning false. That is correct behaviour — an
app with no Zig runtime is the shim-only configuration, not an error — but it
threw away the dynamic linker's explanation on the way.

The first time the runtime was genuinely shipped and genuinely failed to load,
that cost a whole CI cycle: the APK carried lib/x86_64/libcraft.so, the app
launched, all four bridge cases passed, and the entire evidence for what went
wrong was that `CraftNative` never appeared in logcat. No linker line, no
exception, nothing.

Both outcomes are logged now, under the same tag Zig's own output uses, so the
pair reads as a sequence: "libcraft.so loaded" then "registered 59 natives"
means bound; the first without the second means it loaded and failed to bind;
neither means it never loaded, and the warning carries the linker's own
complaint about why.
