:rocket: Roadmap for 0.1 release

[daquintero]

• Coverage of all new non-simulation code (since this will change in 0.2) working from the nix CI.
• Working nix release with the venv. Migrate the poetry2nix implementation to uv #122
• Automatic experimental relevant time signal extraction and automated metrics #127 (will take a bit more effort to properly impelement)
• Improved experimental analytics functionality #134
• 🔧 Fix multiple ports bug gdsfactory/gdsfactory7#19 means it's possible to now do a gdsfactory7 compatible release.
• Upgrade all code to the new version of gdsfactory7 accordingly.

I'm inclined to do a few small patch releases and get a final 0.1 release that is fully stable, before completely migrating the backend simulation and experimental classes equivalence in 0.2
