Route playerbot turns through explicit lifecycle

[adrunkhuman]

Summary

• Route each controller turn through a pure priority contract while the controller retains engine-facing execution.
• Distinguish paused restart checkpoints from terminal stops, prevent post-terminal turns, and separate navigation reset from hunt-planning cancellation.
• Preserve bounded suspended-loot retries and document the lifecycle, routing, and telemetry contracts.

Verification

• docker compose -f server/compose.yaml build server - passed
• Focused lifecycle, planning, navigation, and loot scenarios - 7/7 passed
• real_depot_restart_deposit with the paused-state telemetry assertion - passed
