Agentic PRD batch

When the user says process PRDs, run batch from PRD folder, process the queue, or similar, or when editing files in .agent/queue/ with intent to implement:

1. Locate specs: Look for PRD/spec files in the configured path (e.g. .agent/queue/ or structured in/ under queue root). Exclude README, INDEX, SPEC-TEMPLATE. Filter by front matter status == ready (or in-progress if resuming). Sort by priority (high first), then filename date (oldest first). Version mismatch: If a spec has localsetup_framework_version and it differs from repo root VERSION, surface a warning per protocol; do not silently ignore.
2. Implement per spec: Load each spec; follow Implementation steps and Acceptance criteria; satisfy Verification plan and Rollback plan. Use PRD schema and _localsetup/docs/PRD_SCHEMA_EXTERNAL_AGENT_GUIDE.md for format and outcome template.
3. Update status: Set spec status: in-progress when starting; set status: done (or blocked) when finished. Update queue INDEX if present.
4. Write outcome: Append outcome block per spec (e.g. ## Outcome or platform-specific section name, and/or aq_outcome YAML) with branch, commit SHA, files changed, verification, rollback command. See PRD_SCHEMA_EXTERNAL_AGENT_GUIDE for template.
5. Clean-tree invariant: Before marking a spec done, ensure repo is clean (no modified tracked files except intended commits; untracked queue specs allowed). Commit or revert as needed.
6. External confirmation: If spec front matter includes external_confirmation: acknowledged or impact_review: confirmed_by: external_agent, agent may skip human impact confirmation; otherwise follow guardrails (impact summary + user confirmation for big/destructive changes).
