agra fa7c07faf8 fix: comptime reg->value bridge for array-in-aggregate + clean abort on comptime-init failure (issue 0167) ...

(C) regToValue (comptime_vm.zig) gained no array arm, so a #run returning
an aggregate containing an array bailed 'reg->value: aggregate shape not
bridged yet'. Add an .array arm: read N elements at stride
typeSizeBytes(elem) from the array address, bridge each recursively via
regToValue -> an .aggregate Value (serializeAggregateValue already emits
arrays). Composes with struct fields, nested arrays, array-of-structs,
and the ?Arr optional payload; unbridgeable elements bail loudly.

(E) A global failing #run proceeded into LLVM emission and panicked
'unresolved type reached LLVM emission' when the unresolved const was
used. Add 'if (self.comptime_failed) return;' in emit() after Pass 0 so
it aborts cleanly (exit 1, the comptime diagnostic) across run/ir/build.

Regression: examples/comptime/0644-comptime-run-array-aggregate.sx.
Verified by 3 adversarial reviews, suite 793/0. Filed separate bugs found
during review: 0181 (optional-chain ?. to array field + index panics),
0182 (body-local #run unbridged silently miscompiles).
