Deterministic plan.json validation via Python script, replacing most plan-validator agent calls. Performs JSON parsing, schema validation, task checkbox regex, required section checks, sync validation, and data extraction. Only semantic consistency checks (storage/query alignment) require the LLM agent. Triggers on: plan validation, checking plan format, extracting plan data. Returns PLAN_VALID with extracted data or PLAN_FORMAT_ISSUES with issues list.
