Zed Editor adds multiple edit prediction providers and pluggable architecture

Zed Editor now allows users to switch between multiple edit prediction providers, including Zeta, Mercury Coder, Sweep, Ollama, Codestral, and GitHub Copilot's Next Edit Suggestions. The new pluggable provider architecture streamlines integrating additional models and custom solutions. Ollama support is live, enabling local use of open-weight models like CodeLlama and DeepSeek, offering improved privacy and control.
