Add run/ports.go: the host seams the executor will consume, every one
nil-safe so a light host runs with the zero Ports (no persistence/audit/
budget/critic/delegation/delivery) and a heavy host wires each to a battery.
Ports mirror mort's existing interfaces so the batteries implement them
directly:
- Audit + RunRecorder (mort skillaudit.Storage/Writer): StartRun -> per-run
recorder (OnStep/OnTool/LogEvent/Close), recorder satisfies RunTally.
- Budget (mort skillexec.BudgetTracker): Check / Commit.
- Critic + CriticHandle (mort agentcritic): Monitor -> handle with
RecordStep/RecordToolStart/Steer/Deadline/Stop (the loop wiring finalizes
with the executor merge).
- Checkpointer (mort agentexec.RunCheckpointer): Save/Complete/Fail.
- PaletteSource (mort SkillInvokerForPalette + AgentInvokerForPalette):
Resolve/Invoke skill + agent delegation.
Plus host-neutral RunInfo / RunStats.
This completes the P2 inversion DESIGN; the agentexec+skillexec ->
run.Executor merge that consumes these Ports is the remaining P2 work.
