Context

Part of kcenon/common_system#685 (Wave 1, P0). Tests reference: container_system.

Problem

• no dedicated fuzz/ for SQL parser/serialization/protocol decoders (security-sensitive -> audit risk)
• committed build artifact integration_tests/cmake_test_discovery_*.json
• integration tests duplicated (tests/integration_tests.cpp vs top-level integration_tests/)

Acceptance Criteria

• dedicated fuzz/ harness + corpus + weekly fuzzing workflow
• build artifact removed and .gitignore updated
• integration tests consolidated; duplicate workflows merged

Notes

Weekly fuzzing workflow touches .github/workflows/ -> requires workflow token scope. The artifact removal + .gitignore part does not.
