Add TinyTools (free browser-based AI utilities) to Marketing & SEO and Open Source sections

[alfredoautomatizaloconia-cloud]

Hi @ShaikhWarsi 👋 — adding TinyTools, a small collection of free, browser-based utilities (no signup, no tracking). I picked the three most relevant for this list:

• SEO Meta Tag Generator and AI Robots.txt Generator → Marketing & SEO Tools (the robots.txt tool generates rules for GPTBot, ClaudeBot, Google-Extended, PerplexityBot, etc. which feels on-topic for a 2026 free AI tools list)
• OG Image Generator → also Marketing & SEO Tools
• AI Background Remover → Open Source & Local Tools (runs entirely in the browser via ONNX Runtime, no server upload)

All tools are open source, free, and require no signup or credit card. Happy to remove/relocate any entry that you feel is off-topic.
