This PR is a long ways from running, let alone being stable.Closes#1059. Rather than merging this in, I'll rename the currentmain branch tov1 and rename this branch tomain.

V2 Overall goals:

• Remove sources in favor of LSPs
  • Include compat layer for existing blink.cmp sources to in-process LSPs
  • Promote building in-process LSPs across the ecosystem (include boilerplate)
• Simplify codebase as much as possible
  • Consider removing auto brackets, LSPs should support this themselves
  • Switch keymap system tovim.on_key
  • User callscmp.download() to download prebuilt-binaries orcmp.build() to build from source. No automatic download
  • Drop custom documentation rendering, in favor of vim.lsp.utils.convert_input_to_markdown_lines (we have conceal lines now!)
• Adopt vim.task:https://github.com/lewis6991/async.nvim
• First-class vim help documentation
• Adoptiskeyword for keyword regex by default
• Synchronous API when possible

Configuration goals:

• Programmatic over declarative
• Follow neovim patterns as much as possible (refer tovim.lsp.*,vim.lsp.inlay_hint.*, etc.)
• Easily configure per-buffer, per-LSP, and dynamically
• First-class vim.pack support
• Allon_* event handlers also emitUser autocommands
