Add Agent Fabric controlled capture corpus

[moonweave]

Summary

• add a source-only Agent Fabric controlled capture corpus report and CLI
• allow dogfood evidence CLI to summarize repeated capture manifests as a controlled corpus
• add a second docs/source-only observed capture fixture and V123 release-contract updates

Verification

• python3 -m py_compile depone/agent_fabric/controlled_capture.py depone/agent_fabric/dogfood_evidence.py depone/cli/agent_fabric_controlled_capture.py depone/cli/agent_fabric_dogfood_evidence.py depone/__main__.py scripts/dwm_roadmap_reconciliation.py scripts/dwm_workflow_activation.py scripts/dwm_workflow_narrative.py scripts/check_contract.py
• PYTHONPATH=. python3 tests/test_agent_fabric_controlled_capture.py
• PYTHONPATH=. python3 tests/test_agent_fabric_dogfood_evidence.py
• python3 -m depone agent-fabric-controlled-capture --self-test
• python3 -m depone agent-fabric-dogfood-evidence --self-test
