Verified the context assembly CLI commands (context list, add, show, clear)
are fully functional and integrated with ContextService and the DI container.
Both Robot E2E acceptance tests (ACMS Scoped Context Output Per Phase and
Context Policy Clear And Inheritance Fallback) pass, confirming phase-scoped
view resolution, size limit narrowing, inheritance fallback on clear, and
persistence round-trip correctness.
Added 5 new Behave scenarios to m5_acms_smoke.feature covering the required
unit test patterns: multiple resources management (list, add, show with
multiple files), clear-then-re-add flow, and clear on empty project. All
12,235 unit test scenarios pass. Coverage is 98.38% (threshold >97%).
