fix(autoplan): publish each phase report with a no-op call; foreground requests are conditional

Phase-close step 6 sends the report in a message whose only tool call is
the Bash no-op ': autoplan-published <phase>', and step 7 makes the next
guarded call in a later message, so the guard sees the report flushed
before the next phase entry regardless of Claude Code's journal timing.

Every site that asked for run_in_background: false now asks for it only
when the Agent schema offers it and says how to recover when a dispatch
runs in the background anyway (wait for its completion notice). Parity
caps rise by the measured bytes.
