18 obj-c examples migrated (1308/1311-1317/1319/1320/1321/1341-1347): import
runtime classes '#foreign #objc_class("X") {' → '#objc_class("X") extern {'
(prefix→postfix) + fn/comment '#foreign'→'extern'. No 13xx snapshot asserts on
'foreign' text → all behavior-preserving; empty snapshot diff, corpus-validated.
Per the keep-list policy: KEPT identity-#foreign tests 1306/1318 (filename
ffi-*-foreign*); LEFT comment-only #foreign in the extern/export test files
1332/1348/1349 (no decls). Bare defined #objc_class examples (no #foreign) untouched
— not a purge target. Suite green (647 corpus / 444 unit, 0 failed).

// Phase 3 step 3.0: one-arg selector mangling. `addObject(o)` derives

// `addObject:` — the sx method name becomes the keyword, a single
|
|
// trailing `:` for the single arg. Selector arity (count of `:`) must
|
|
// equal sx-side arity excluding self.

// Pre-3.0: bails at lower.zig with the Phase 3/4 diagnostic.
