agra 1a8991ab27 refactor(ffi-linkage): Phase 7.4 — migrate straggler examples #foreign→extern
16 fn/global examples across categories (0415/0602/0603/1024/1025/1605/1607-1609/
1611/1616/1619/1622/1628/1635/1636): bare '#foreign'→'extern'. All cls=0 (no class
forms). Marker'd ones (1605/1609/1611 + the rest) corpus-validated; the 3 unmarked
uikit importers (1607/1608/1616) verified byte-identical via 'sx ir' probes.
Empty snapshot diff; suite green (647 corpus / 444 unit, 0 failed).

LEFT comment-only/provenance #foreign (0716/0729 + issues/0030-extern-global +
extern-test files 1223-1231/1332/1348/1349/1426) and the keep-list (identity
ffi-foreign-* + foreign-asserting diagnostics 1172/1174/1219/1228/1620) for Phase 8.

// Two `#import c` units defining the same exported symbol is a

// All units share one link namespace; per-unit symbol isolation is
// PLAN-C C3.2 (deferred).
