v10.45 - Subagent-Driven-first execution routing

Summary

• make selected non-trivial plan-backed or goal-backed work prefer Subagent-Driven first after a checked suitability gate
• preserve Inline Execution only as a checked direct-handling exception when more effective for the current slice
• keep /goal as objective owner and plan files as route-only support while syncing the touched runtime and release surfaces

Verification

• git diff --check
• touched runtime install/update verification with source/runtime parity + body sufficiency
• push/update to master
• tag and release verification for v10.45
