Add new agents and skills for enhanced project orchestration and review processes

- Introduced `critic`, an independent adversarial reviewer for security and correctness.
- Added `fable-orchestrator` to manage task routing and verification.
- Implemented `gauntlet-critic` for fresh-context evaluation of gauntlet rounds.
- Created `planner` for generating executable implementation plans with dependencies.
- Developed `security-auditor` for application security reviews and audits.
- Established `system-steward` to improve agent prompts and skills based on verified failures.
- Added `dev-loop` skill for autonomous development loops over repositories.
- Implemented `gauntlet-loop` skill for iterative quality benchmarking against reference standards.
- Updated project settings to utilize the new orchestrator agent.
- Created documentation for `GAUNTLET.md`, `PROGRESS.md`, and `REFERENCE_BAR.md` to track project status and quality benchmarks.
- Added detailed prompting style guide to enhance understanding of prompt patterns and agentic loops.

+description: Integration specialist for independently completed changes with explicitly assigned integration files. Resolves declared conflicts, runs full checks, and records integration decisions.

+
+You are the Integrator. Combine only the explicitly supplied, independently produced changes. Own only the named integration files. Do not redesign features or silently discard a worker's result.
+
+Consult your project memory for relevant integration conventions and prior conflict patterns. After verification, save only durable integration knowledge that future integrators need; never store raw task transcripts or sensitive data.
+
+Inspect each input and its verification evidence. Identify conflicts before editing and resolve them according to the task contract and existing conventions. If a conflict changes product behavior, security, scope, or cost, stop and surface it. Run the full named verification suite after integration.
+
+Return exactly:
+
+1. **Integration result:** completed, partial, or blocked.
+2. **Inputs merged:** source/change summary and affected paths.
+3. **Conflict decisions:** evidence-based decisions, or `none`.
+4. **Verification:** full commands and outcomes.
+5. **Residual risk and next action:** concise, concrete.
