--------------------------------

### Opencode Client Initialization and Session List

Source: https://pkg.go.dev/github.com/sst/opencode-sdk-go

Demonstrates how to initialize the Opencode client and list sessions using the SDK.

```APIDOC
## Opencode Go API Library

The Opencode Go library provides convenient access to the Opencode REST API from applications written in Go.

#### Installation
```go
import (
	"github.com/sst/opencode-sdk-go" // imported as opencode
)
```

Or to pin the version:
```go
go get -u 'github.com/sst/opencode-sdk-go@v0.19.2'
```

#### Requirements
This library requires Go 1.22+.

#### Usage
```go
package main

import (
	"context"
	"fmt"

	"github.com/sst/opencode-sdk-go"
)

func main() {
	client := opencode.NewClient()
	sessions, err := client.Session.List(context.TODO(), opencode.SessionListParams{})
	if err != nil {
		panic(err.Error())
	}
	fmt.Printf("%+v\n", sessions)
}
```

##### Request fields
All request parameters are wrapped in a generic `Field` type, which we use to distinguish zero values from null or omitted fields. This prevents accidentally sending a zero value if you forget a required parameter, and enables explicitly sending `null`, `false`, `''`, or `0` on optional parameters. Any field not specified is not sent.
To construct fields with values, use the helpers `String()`, `Int()`, `Float()`, or most commonly, the generic `F[T]()`. To send a null, use `Null[T]()`, and to send a nonconforming value, use `Raw[T](any)`. For example:
```go
params := FooParams{
	Name: opencode.F("hello"),

	// Explicitly send `"description": null`
	Description: opencode.Null[string]()

	Point: opencode.F(opencode.Point{
		X: opencode.Int(0),
		Y: opencode.Int(1),

		// In cases where the API specifies a given type,
		// but you want to send something else, use `Raw`:
		Z: opencode.Raw[int64](0.01), // sends a float
	}),
}
```

##### Response objects
All fields in response structs are value types (not pointers or wrappers). If a given field is `null`, not present, or invalid, the corresponding field will simply be its zero value.
All response structs also include a special `JSON` field, containing more detailed information about each property, which you can use like so:
```go
if res.Name == "" {
	// true if `"name"` is either not present or explicitly null
	res.JSON.Name.IsNull()

	// true if the `"name"` key was not present in the response JSON at all
	res.JSON.Name.IsMissing()

	// When the API returns data that cannot be coerced to the expected type:
	if res.JSON.Name.IsInvalid() {
		raw := res.JSON.Name.Raw()

		legacyName := struct{
			First string `json:"first"`
			Last  string `json:"last"`
		}{}
		json.Unmarshal([]byte(raw), &legacyName)
		name = legacyName.First + " " + legacyName.Last
	}
}
```

These `.JSON` structs also include an `Extras` map containing any properties in the json response that were not specified in the struct. This can be useful for API features not yet present in the SDK.
```go
body := res.JSON.ExtraFields["my_unexpected_field"].Raw()
```

##### RequestOptions
This library uses the functional options pattern. Functions defined in the `option` package return a `RequestOption`, which is a closure that mutates a `RequestConfig`. These options can be supplied to the client or at individual requests. For example:
```go
client := opencode.NewClient(
	// Adds a header to every request made by the client
	option.WithHeader("X-Some-Header", "custom_header_info"),
)

client.Session.List(context.TODO(), ...,
	// Override the header
	option.WithHeader("X-Some-Header", "some_other_custom_header_info"),
	// Add an undocumented field to the request body, using sjson syntax
	option.WithJSONSet("some.json.path", map[string]string{"my": "object"}),
)
```

See the full list of request options.
##### Pagination
This library provides some conveniences for working with paginated list endpoints.
You can use `.ListAutoPaging()` methods to iterate through items across all pages:
Or you can use simple `.List()` methods to fetch a single page and receive a standard response object with additional helper methods like `.GetNextPage()`, e.g.:
```

// Assuming 'client' is an initialized opencode.Client
// This sets the timeout for the request, including all retries.
ctx, cancel := context.WithTimeout(context.Background(), 5*time.Minute)
defer cancel()

client.Session.List(
