SessionStart

SessionStart nudge directing the agent to delegate data-engineering tasks to altimate-code via the altimate-code skill. The UserPromptSubmit pre-run hook was removed because it double-invoked altimate-code (once at hook time, once when the model fired the skill), doubling token consumption on the al
