## Summary Persisted subagent parent/child topology currently leaks through `StateRuntime`'s SQLite-specific thread-spawn helpers. This PR introduces a narrow `AgentGraphStore` boundary so follow-up work can route graph operations through a local or remote store without coupling orchestration code directly to the state DB graph API. ## Changes - Adds the new `codex-agent-graph-store` crate. - Defines a flat `AgentGraphStore` trait for the v1 graph surface: upsert edge, set edge status, list direct children, and list descendants. - Adds public graph types for `ThreadSpawnEdgeStatus`, `AgentGraphStoreError`, and `AgentGraphStoreResult`. - Implements `LocalAgentGraphStore` on top of an existing `codex_state::StateRuntime`, preserving today's SQLite-backed `thread_spawn_edges` behavior. - Registers the crate in Cargo/Bazel metadata. This PR only adds the local contract and implementation; call-site migration and the remote gRPC store are left to the follow-up PRs in the stack. ## Testing - `cargo test -p codex-agent-graph-store` The new unit tests cover local parity with the existing `StateRuntime` graph methods, `Open`/`Closed` filtering, status updates, and stable breadth-first descendant ordering.
