Fix stem_memory coverage reporting and raise threshold

[kingwill101]

Summary

• add stem_memory unit tests that exercise every factory in memory_factories.dart
• cover both broker dispose paths (InMemoryBroker.dispose and fallback Broker.close)
• raise stem_memory workflow coverage threshold from 0 to 80

Verification

• cd packages/stem_memory && dart test
• cd packages/stem_memory && dart test --coverage=coverage --fail-fast
• cd packages/stem_memory && dart run coverage:format_coverage --lcov --in=coverage --out=coverage/lcov.info --report-on=lib
• cd packages/stem_memory && dart run ../../tool/coverage/coverage_badge.dart --lcov coverage/lcov.info --out coverage/coverage.json --min 80

Closes #14
