Apply changes from nightly

[ej-shafran]

This pull request includes the changes which will make up version 4.0.0.

The two main changes in this version are the deprecation of setup() and the change in error-jumping behavior.

setup Deprecation

setup() has been deprecated as the way to configure the plugin - instead, users of the plugin should set the vim.g.compile_mode table to their configuration options, like so:

- require("compile-mode").setup {
+ ---@type CompileModeOpts
+ vim.g.compile_mode = {
     -- options go here
 }

(Depending on your Lua LSP, you may need to add ---@module "compile-mode" for the ---@type CompileModeOpts type annotation to work)

As of 4.0.0, the setup function will continue to work, but it will log a warning.

⛔️ The setup function will be removed entirely in version 5.0.0 ⛔️

Error-jumping Behavior

The splitting behavior for jumping to errors has been changed; the new behavior mimics the way the Emacs mode works - use the current window, unless that window is the compilation buffer, in which case use another existing window or create a split if none exists - but enables the usage of commands like :vertical and other modifiers to determine the manner in which splits occur.
