feat(08-02): add 25 GitHub dorks for frontier and specialized categories
- frontier.yaml: 15 dorks covering Tier 1/2 providers (OpenAI, Anthropic,
Google AI, Azure OpenAI, AWS Bedrock, xAI, Cohere, Mistral, Groq,
Together, Replicate)
- specialized.yaml: 10 dorks covering Tier 3 providers (Perplexity,
Voyage, Jina, AssemblyAI, Deepgram, ElevenLabs, Stability, HuggingFace)
- Extend loader to accept YAML list format in addition to single-dork
mapping, enabling multi-dork files for Wave 2+ plans
- Mirror all YAMLs into dorks/github/ (user-visible) and
pkg/dorks/definitions/github/ (go:embed target)
