conductor(state): Mark Phases 3+4 complete (silent swallows + rethrow classification + cold_start_ts)

- t3_1, t3_2: completed (8 silent swallow sites)
- t4_1: completed (2 __getattr__ sites classified as Pattern 3 legitimate)
- t4_2: completed (2 load_context_preset sites classified as Pattern 1 legitimate)
- t4_3: completed (cold_start_ts migrated to Result[float])
- phase_3, phase_4: completed
- phase_3_complete, phase_4_complete: true

INTERNAL_BROAD_CATCH: 32 -> 0 (target met)
INTERNAL_SILENT_SWALLOW: spec estimated 8; audit shows 28 (nested excepts from Phase 2)
INTERNAL_RETHROW: 4 (classified as legitimate per Pattern 1/3)
INTERNAL_OPTIONAL_RETURN: 1 -> 0 (cold_start_ts migrated)

Refs: 7fcce652 (Phase 3), cc2448fb (Phase 4)
