[codex] Switch control plane to embedded triple store

[pcharbon70]

Summary

This PR implements the embedded TripleStore control-plane cutover plan section by section.

• expands the control-plane ontology and replaces stale forge ontology references with execution-runtime/product-specific terms
• adds the phased implementation plan under planning/embedded-triple-store-control-plane
• adds the embedded control-plane store runtime, product store contract, RDF projection codecs, graph topology, validation, and policy boundary
• cuts setup, auth, security, managed repositories, operations, governance, orchestration, conversations, and execution-runtime persistence over to embedded-store-backed services
• removes Ash/Postgres runtime configuration and test sandbox dependencies from the active product path
• adds control-plane integrity, export, restore, reset, health, telemetry, diagnostics, documentation, static guardrails, and recovery coverage
• adds mix control_plane.verify as the focused persistence-boundary verification gate

Notes

The branch was rebased onto origin/main after the planning PR was merged, so PR #199 is now mergeable. CI is running on the updated branch.
