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.

+# Progress board
+
+> For the owner. What works, how to see it, and what's waiting on you — plain language, no agent jargon. Refreshed at every phase seal and session end. `HANDOFF.md` speaks to the next agent; this page speaks to you.
+
+**Updated:** 2026-08-06 · **Overall:** working MV3 extension (Phase 1 + the 2026-07 fix wave); operating system upgraded to the gauntlet-loop/opus kit today.
+
+## What works now
+
+- The extension itself: selection → floating toolbar → fix/rephrase/shorten/expand/explain/prompt → Replace or Copy; four providers (OpenAI/Anthropic/Groq/OpenRouter); encrypted BYO key; Options with live model listing; Prompt Builder; 58/58 unit tests, typecheck and build green (2026-07-23).
+- The agent operating system: upgraded from the older fable kit — 13 specialists (incl. your custom `lexai-extension-dev`, kept and modernized) + 4 new ones (ux-ui-designer, ux-psychologist, and the fresh-eyes `gauntlet-critic` referee), 12 skills, all your lessons and security-auditor memory preserved. Lead is now `claude --agent opus-orchestrator`.
+
+## See it yourself
+
+- `npm run build` → `chrome://extensions` → Load unpacked → `.output/chrome-mv3` → select text on any page.
+- Open `CLAUDE.md` — your repo rules and 9 codebase invariants are carried over intact; the gauntlet protocol is new in §3.
+
+## Waiting on you — each item blocks ONLY its own lane
+
+| # | Decision | Options (recommended bold) | What it unblocks |
+| --- | --- | --- | --- |
+| 1 | Groq-key re-entry check (from 2026-07-23 handoff): reload unpacked, re-enter Groq key in Options, ↻ Load → model → Save, confirm a real-page action | **do the 5-min check** / report it already done | closes the key-mismatch fix loop |
+| 2 | Supply reference-bar artifacts (screenshots/recording of Grammarly or your chosen benchmark → `docs/reference/`) | **Grammarly toolbar + card screenshots** / pick another benchmark / defer gauntlets | UI gauntlet rounds |
+| 3 | Approve the Replace-reliability site matrix in `docs/REFERENCE_BAR.md` (Gmail, GitHub, X, LinkedIn, Google Docs?, Reddit, Notion) | **approve as listed (Docs out of scope)** / edit the list | the behavioral gauntlet — can start without screenshots |
+| 4 | Set gauntlet budgets on `docs/GAUNTLET.md` | **modest budget on one part first** / several at once | looping |
+| 5 | Delete `_to_delete\` in the repo (replaced kit files + transfer archive parked there) | delete now / leave for later | nothing — housekeeping |
+
+## Next up — proceeds without you
+
+- T-01 (`<all_urls>` narrowing) and T-02 (real key encryption) remain the ranked pre-release risks from `HANDOFF.md` — routable to security-auditor + lexai-extension-dev any time.
