To be done before merging

We need a better "validate" documentation pipeline, need to review this one and fix it.

Use ai agent with correct context to ensure this automatically ?

[aeppling]

Recap':

• Rework of all cicd flow, re-using some component for building and release
• Add pre-release stage
• Add 3 platforms testing
• Removed shady doc testing for a ai agent reviewer (using for now my own API key with 10$ limit / month)
• Added CONTRIBUTING.md guidelines about PRs scope and big feat or refacto split
• Fixed failing windows test for git and binlog commands support
• Added documentation for CICD flow
