WIP: enforce buffer ordering in multibuffer

# Add AnyBrackets text object for Vim mode

## Overview
This PR introduces a new text object `AnyBrackets` that allows
operations on the closest matching pair of brackets, regardless of the
bracket type. This enhances the editing experience by reducing the need
to identify specific bracket types before performing text operations.

By default, this feature is NOT mapped to any key in vim.json. However,
it can be enabled manually, and the recommended key for mapping is b:

If you want to add it to your zed keymap config you need to add the
following config:
```json
{
	"context": "vim_operator == a || vim_operator == i || vim_operator == cs",
	"bindings": {
		"b": "vim::AnyBrackets"
	}
}
```

## Features
- New text object that works with parentheses `()`, square brackets
`[]`, curly braces `{}`, they are also know as round brackets, square
brackets and curly brackets in english.
- Automatically finds the closest matching pair of any bracket type
- Works with all standard Vim operators (delete, change, yank)
- Supports both "inside" and "around" variants (`i` and `a`)

## Usage Examples
```vim
# Delete inside the closest brackets
di(  # Works on (), [] or {} depending on which is closest

# Change around the closest brackets
ca[  # Works on (), [] or {}  depending on which is closest

# Visual select inside the closest brackets
vi{  # Works on (), [] or {}  depending on which is closest
```

# References:
- Based on the popular plugin https://github.com/echasnovski/mini.ai

# Important Notes
This PR also fixes a bug with nested quotes on AnyQuotes, now it works
fine with any type of quotes or brackets.
Please take a look at the new tests to understand the expected behavior.

Release Notes:

- vim: Add `ab`/`ib` "AnyBrackets" text objects that are the smallest of
`a(`, `a[` or `a{` or `i(`, `i[` or `i{`
- vim: Fix aq/iq "AnyQuotes" text objects when they are nested

-        1. We import necessary items from the `actix-web` crate.
-        2. We define an async `hello` function that returns a simple HTTP response.
-        3. In the `main` function, we set up the server to listen on `127.0.0.1:8080`.
-        4. We configure the app to respond to GET requests on the root path with our `hello` function.

-            thread.insert_message(Role::Assistant, "Certainly! Async functions are a key feature in Rust for writing efficient, non-blocking code, especially for I/O-bound operations. Here's an overview:
-
-        1. **Syntax**: Async functions are declared using the `async` keyword:
-
-           ```rust
-           async fn my_async_function() -> Result<(), Error> {
-               // Asynchronous code here
-           }
-           ```
-
-        2. **Futures**: Async functions return a `Future`. A `Future` represents a value that may not be available yet but will be at some point.
-
-        3. **Await**: Inside an async function, you can use the `.await` syntax to wait for other async operations to complete:
-
-           ```rust
-           async fn fetch_data() -> Result<String, Error> {
-               let response = make_http_request().await?;
-               let data = process_response(response).await?;
-               Ok(data)
-           }
-           ```
-
-        4. **Non-blocking**: Async functions allow the runtime to work on other tasks while waiting for I/O or other operations to complete, making efficient use of system resources.
-
-        5. **Runtime**: To execute async code, you need a runtime like `tokio` or `async-std`. Actix-web, which we used in the previous example, includes its own runtime.
-
-        6. **Error Handling**: Async functions work well with Rust's `?` operator for error handling.
-
-        Async programming in Rust provides a powerful way to write concurrent code that's both safe and efficient. It's particularly useful for servers, network programming, and any application that deals with many concurrent operations.".unindent(), cx);
