Wire Gcinfer.infer into runner.ml's owner_str/emit_str so the unit tests classify GC-ness identically to the driver (prerequisite for removing @gc: its tests read the golden .wo through the library). That exposed owner-err/borrow-escape.wo, which tested WO-E304 on *class* escapes — now legally demand-promoted. Retargeted it to CONTAINER (`multi Text`) escapes, which are owned and never promoted, so it still exercises the three WO-E304 shapes (stored-in-field, returned, moved-to-take). Assertion positions + golden re-blessed. Verified: woc-test 566/0, test_diag 14/0, oop-e2e 79/0. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

-- Iteration 7b: WO-E304 borrow escapes, using CONTAINER values (`multi Text`).
