Migrate the DECLS of the 7 identity-#foreign feature tests to extern/export
(1205-global/-helper, 1207, 1218-cvariadic, 1219, 1306, 1318): fn/global markers →
extern, the 2 objc import classes (1306/1318) → postfix '#objc_class("X") extern {'.
Behavior-preserving (A→B gate + existing extern twins guarantee identical output);
empty snapshot diff, corpus-validated. Comment-only #foreign in these files is left
for the Phase 9.3 doc/comment purge (comments aren't parsed → not cutover-critical).
Suite green (647 corpus / 444 unit, 0 failed).

// Chained foreign-class method dispatch: `Cls.static().instance(...)`
|
|
// resolves the inner call's return type so the outer dispatch's
|
|
// receiver type is known. Pre-fix this collapsed to i64 in
|
|
// `inferExprType`, the foreign_class_map lookup missed, and lowering
|
|
// emitted `error: unresolved 'init'` (or 'initWithWindowScene' etc.)
|
|
// — see issues/0043 for the chess uikit.sx C4 migration that hit it.
|
|
//
|
|
// Two return-type shapes covered: explicit `*ClassName` (alloc here)
|
|
// and `*Self` (init). Both must propagate through the chain so the
|
|
// next `.method(...)` finds the foreign-class declaration.
