Add GROWTH.md — Community Growth Playbook

[Gingiris]

👋 Hi DeepAnalyze team!

I've been following your project and really impressed by what you've built — the first fully open-source agentic LLM for autonomous data science is a significant contribution to the community.

What this PR adds

A GROWTH.md file with practical strategies to increase visibility and grow the community:

• Awesome-list submissions — DeepAnalyze isn't yet listed in major lists like awesome-ai-agents, Awesome-LLM, or awesome-generative-ai. I've prepared submission templates.
• Reddit/HN posting strategies — Title options and content templates optimized for different communities (r/LocalLLaMA, r/datascience, r/MachineLearning)
• Content calendar — Weekly/monthly activities to maintain momentum
• Metrics tracking — What to measure and realistic targets
• Contributor growth — Good first issues and partnership ideas

Why I'm contributing this

As someone who helps open-source projects grow, I see DeepAnalyze has strong fundamentals (academic backing, full openness, clear differentiation) but could benefit from more structured community outreach. With 3.8K stars, you're at an inflection point where the right visibility push could accelerate growth significantly.

Notes

• This is meant as a starting point — please adapt, modify, or cherry-pick whatever is useful
• Happy to discuss or help with implementation
• Feel free to close if this doesn't fit your roadmap

Cheers! 🚀
