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.

-Operate a controlled maintenance loop that makes steady, verified progress without human babysitting — and without ever landing unverified or unauthorized work. Fable owns routing and acceptance; this skill is the loop discipline. Adapt the cadence to the runtime: a live session iterates continuously; a scheduled run (see the `schedule` skill) executes one pass per trigger.
