Module automation 

Minimal session-scoped automation above crate::runtime::Session.

V1 keeps the boundary intentionally small:

• automate one prepared Session
• schedule with absolute SystemTime boundaries plus one fixed Duration
• require every > Duration::ZERO
• run at most one prompt turn at a time
• collapse missed ticks into one next eligible run
• stop permanently on stop(), stop_at, max_runs, closed session, or any crate::runtime::PromptRunError

Non-goals for this module:

• no cron or human-time parsing
• no session creation or resume orchestration
• no persistence or restart recovery
• no retry or downgrade policy for prompt failures
