zed_extension_api: Bump to v0.1.0 (#16158)
This PR changes v0.0.7 of the extension API to v0.1.0.

We had a false-start in releasing v0.0.7, which has since been yanked,
so we need a new version number. We'll publish v0.1.0 to crates.io once
the Preview build is out tomorrow.

We're incrementing the minor version so that we have some leeway in
putting out patch releases of the crate within a given extension API
release.

# The Zed Rust Extension API
This crate lets you write extensions for Zed in Rust.
## Extension Manifest
You'll need an `extension.toml` file at the root of your extension directory, with the following structure:
```toml
id = "my-extension"
name = "My Extension"
description = "..."
version = "0.0.1"
schema_version = 1
authors = ["Your Name <you@example.com>"]
repository = "https://github.com/your/extension-repository"
```
## Cargo metadata
Zed extensions are packaged as WebAssembly files. In your Cargo.toml, you'll
need to set your `crate-type` accordingly:
```toml
[dependencies]
zed_extension_api = "0.1.0"
[lib]
crate-type = ["cdylib"]
```
## Implementing an Extension
To define your extension, create a type that implements the `Extension` trait, and register it.
```rust
use zed_extension_api as zed;
struct MyExtension {
// ... state
}
impl zed::Extension for MyExtension {
// ...
}
zed::register_extension!(MyExtension);
```
## Testing your extension
To run your extension in Zed as you're developing it:
- Open the extensions view using the `zed: extensions` action in the command palette.
- Click the `Install Dev Extension` button in the top right
- Choose the path to your extension directory.
## Compatible Zed versions
Extensions created using newer versions of the Zed extension API won't be compatible with older versions of Zed.
Here is the compatibility of the `zed_extension_api` with versions of Zed:
| Zed version | `zed_extension_api` version |
| ----------- | --------------------------- |
| `0.149.x` | `0.0.1` - `0.1.0` |
| `0.131.x` | `0.0.1` - `0.0.6` |
| `0.130.x` | `0.0.1` - `0.0.5` |
| `0.129.x` | `0.0.1` - `0.0.4` |
| `0.128.x` | `0.0.1` |
