Token usage analytics

Implementation

Execute Output

Status: blocked. The plan assumes prerequisites absent from this worktree:

• No Hive::RuntimeControlPlane
• No task_subjects table
• No existing token_usage.task_id foreign key
• UsageDb still owns standalone schema v4

Those prerequisites exist only on divergent branch feat/sqlite-runtime-control-plane at 00d1804202 (11 current-only / 6 prerequisite-only commits). Implementing here would require silently importing that major architecture and migration, contradicting the plan.
