refactor(ffi-linkage): Phase 7.1 — migrate incidental 12xx ffi examples #foreign→extern

Browse Source 
12 plain-C examples that use #foreign incidentally (as FFI plumbing, output
unchanged): 1200/1206/1209-1215/1220/1221/1222. Blanket keyword swap; all fn/global
markers (no class forms in 12xx). Empty snapshot diff; corpus validates directly
(all marker'd). Suite green (647 corpus / 444 unit, 0 failed).

KEPT on #foreign (deferred to Phase 8 cutover): identity-#foreign feature tests
(filename ffi-foreign-*: 1205/1207/1216/1218/1219), the equivalence test 1228, and
the diagnostics that assert on #foreign source/message (1172/1174/1620). Comment-only
provenance prose (1223/1229/1230/1231) left intact per Decision-6-recommended.
