agra d3944570b9 lang: generic $R type-arg resolution + receiver-driven ufcs overload (issues 0156, 0157)
0156 Part 1: a single-type generic $R (parsed as comptime_pack_ref)
used as a type-arg in a pack-fn body (Box($R), size_of(Box($R))) hit a
missing arm in resolveTypeWithBindings -> .unresolved -> LLVM panic.
Fix: mirror resolveTypeArg's comptime_pack_ref arm (look up
type_bindings, else a loud diagnostic). Regression: examples/generics/0216.
(Part 2 -- deferred .. spread crashes -- reframed OPEN/non-blocking.)

0157: a user generic ufcs method whose name collides with a stdlib
re-export resolved via last-wins fn_ast_map with no receiver filtering,
so the wrong overload won, $R never bound, and .unresolved reached LLVM.
Fix: selectUfcsGenericByReceiver enumerates all module authors, keeps
the receiver-binding ones, picks the most receiver-specific (concrete >
bare $T), dedups re-exports, and flags a genuine tie as a deterministic
'ambiguous -- qualify' diagnostic. Regression: examples/generics/0217.
