- PlannerMeta is now a discriminated union: planned | aborted
- Moderator routes aborted planner → END (no coder invocation)
- System prompt requires absolute workspace path, instructs abort if missing
- extractRefs handles both variants
- Test: 'planner aborted → END'

Planner, coder, reviewer, and tester system prompts now explicitly
instruct the agent to keep responses short and avoid pasting diffs,
code blocks, or full build logs. This reduces CAS storage and token
waste when downstream roles read the thread.
