Neural v0.1.0

A culmination of various new important features introduced since the first release, alongside some fixes and improvements.

Features

• Add :NeuralBuffer - a full buffer completion playground.
• Add :NeuralExplain - explains a visual selection of code line-by-line.
• Add prompt input preprocessing configurable per filetype. Added default basic prompt preprocessing for the following filetypes:
  • .cmake
  • .cpp
  • .css
  • .go
  • .lua
  • .markdown
  • .python
  • .sh
  • .sql
  • .vim
• Add :NeuralStop to cancel a completion response mid-generation
• Add configurable OpenAI model selection.
• Add support for OpenAI chat API models.

Fix

• Continue to write neural completion response to buffer after switching to another buffer.
• Fix issues with nui prompt cleanup on closing prompt.

Tech

• Improve Vimscript code test coverage.
• Disable macOS certificate verification as a workaround due to API request issues.
• Set gpt-3.5-turbo-instruct as the default model due to OpenAI deprication of older models.

Docs

• Improve documentation on environment variables with KDE and shell scripts.
• Add development documentation.
