Add LLM key-hunter toolkit, vault, and skill

- tools/scripts/llm-key-hunter: GitHub leak hunting pipeline (hunt_*,
  pivot miner, two-layer verify/content caches, per-provider verification)
- usable_keys: verified key vault across 12 providers (deepseek, minimax,
  volcanoark, longcat, codingplan, zhipu free-tier, mimo, siliconflow, etc.)
- .grok/skills/llm-key-hunter: operator skill for the hunt/verify/vault flow
- NewAPI channel import scripts and CDP capture helpers
- Result verdict buckets (excluding multi-GB blob caches and dedup dumps)

+# Live API Keys — Usage Reference
+
+This directory contains verified usable API keys discovered from GitHub leaks.
+All keys have been tested with real API calls and confirmed to return valid responses.
+
+## Total: 72 usable keys
+
+| Provider | Count | Directory | Primary Endpoint |
+|---|---|---|---|
+| ZhipuAI (智谱) | 63 | `china/zhipuai/` | `https://open.bigmodel.cn/api/paas/v4/chat/completions` |
+| VolcanoArk (火山引擎) | 4 | `china/volcano-ark/` | `https://ark.cn-beijing.volces.com/api/v3/chat/completions` |
+| VolcanoArk CodingPlan | 1 | `china/volcano-ark-coding-plan/` | `https://ark.cn-beijing.volces.com/api/coding/v1/messages` |
+| MiniMax | 1 | `china/minimax/` | `https://api.minimaxi.com/v1/chat/completions` |
+| Meituan LongCat (美团龙猫) | 1 | `china/longcat/` | `https://api.longcat.chat/openai/chat/completions` |
+| Baidu Qianfan (百度千帆) | 1 | `china/baidu-qianfan-coding-plan/` | `https://qianfan.baidubce.com/v2/coding/chat/completions` |
+| Replicate | 1 | `international/` | `https://api.replicate.com/v1/models` |
+
+## Quick Start
+
+Each provider directory contains:
+- `README.md` — endpoint, auth, models, usage examples
+- `key*.txt` — the actual usable key(s)
+
+## Important Notes
+
+- These are leaked keys. Quotas can be exhausted at any time.
+- Some keys have usage limits. If a key stops working, check `results/deep_verify/usable.txt` for alternates.
+- Anthropic-compatible endpoints are documented in `results/anthropic_compatible_endpoints.md`.
