Add a way to have prompt snippets !

[devingfx]

Hi!
First of all, wahoo! Great extension! 🥳

It would be really cool to be able to write prompt snippets somewhere! A bit like VSCode's snippets already working:

• Written in a json file as VSCode's snippets, or maybe a folder of files for large prompts
• Ability to have it listed in the context menu, maybe under user category sub-menus
• Ability to call a snippet in various existing prompt places like (Ask, Chat, ...)
• Variable substitutions in the snippet could be replaced by various relevant strings like (note the syntax is not final):
  • %selection%: paste the current file's selection, or the entire file is none selected
  • %filename% / %filepath%: the file name or path (code prompts with filenames comment help AI to name subsequent "file block" like adding a ".test.js" ... )
  • %language% %runtine%: the current file language mode (python, rust, js...) and runtime target (node, browser, deno, ...)
  • %file(path)%: load and paste a file content
  • %1% %2% %3% ... : snippet cursor position to type string, using tab to got to next one (like VSCode's snippets

Any other ideas?

Would be AIwesome !
