Stand up the executus/run kernel foundation, decoupled from mort:
- runengine.go: the shared run-loop scaffolding (MergeCancellation,
CleanupContextTimeout, RunFinalizer/FireFinalizers, RunStateAccessor) moved
from mort. The accessor's *skillaudit.Writer dependency is inverted to a
narrow run.RunTally interface (TokenStats + ToolCallsCount) — the kernel
reads live tallies without importing the audit battery.
- submit.go: the legacy submit-capture compat tool (stdlib + majordomo/llm).
- agent.go: RunnableAgent DTO — the kernel's view of "a thing to run" (tier,
prompt, caps, palette, phases, critic config). The persona Agent and saved
Skill will LOWER into this DTO so the kernel never imports a noun battery.
This is the spine of the agentexec.Run(*agents.Agent) inversion.
run/ builds with only majordomo + executus/tool. The executor merge
(agentexec+skillexec -> run.Executor) and the nil-safe run.Ports
(Audit/Critic/Budget/Checkpointer/PaletteSource) are the next P2 block.
