Implementation Tasks aggregator

Before rendering the Final Approval Gate output block below, aggregate the per-phase task lists each review skill wrote.

Inside the Final Approval Gate output template below, render the aggregated markdown in the ### Implementation Tasks (aggregated across phases) section. Substitute the contents of $AGGREGATED_TASKS (the bash variable set above) before printing the message to the user. This is NOT a template placeholder — the agent does the substitution at runtime, not gen-skill-docs at build time.

If $AGGREGATED_TASKS is empty (no JSONL files found — none of the review skills ran in this session), render:

_No per-phase task lists found in $TASKS_DIR for branch $BRANCH. Each review skill writes its own; if you ran one of them but no list appears here, check that jq is installed and the tasks-<phase>-*.jsonl files exist._
