```
async panes(): Promise<Selection<Pane>>
```

Every pane on the server.

Save this complete program as `panes.ts`. With Bun 1.4.2 or newer,
tmux 3.2a or newer, and `libtmux` installed, run `bun run panes.ts`.
It creates and stops a private tmux server. A failed operation or cleanup
exits with an error; a cleanup error names the retained socket directory.

## Examples

```ts
import { strict as assert } from "node:assert";
import { mkdtemp, readdir, rm } from "node:fs/promises";
import { tmpdir } from "node:os";
import { join } from "node:path";
import { Server, PaneDirection } from "libtmux";

const directory = await mkdtemp(join(tmpdir(), "ltx-example-"));
const server = new Server({
  socketPath: join(directory, "tmux.sock"),
  configFile: "/dev/null",
  timeoutMs: 5_000,
});
const failures: unknown[] = [];
try {
  const session = await server.newSession({
    name: "work",
    windowName: "editor",
    shellCommand: "cat",
  });
  const pane = session.panes.one();
  await pane.split({ direction: PaneDirection.Below, shellCommand: "cat" });
  const panes = await server.panes();
  assert.equal(panes.count(), 2);
  const active = panes.where({ active: true });
  assert.equal(active.count(), 1);
  console.log("panes:", panes.count(), "active:", active.count());
  for (const item of panes) {
    assert.equal(item.session?.name, "work");
    assert.equal(item.window?.name, "editor");
    console.log("location:", item.session?.name, item.window?.name);
  }
} catch (error) {
  failures.push(error);
} finally {
  try {
    if ((await readdir(directory)).includes("tmux.sock")) await server.kill();
    await rm(directory, { recursive: true });
  } catch (error) {
    failures.push(new Error(`Cleanup failed; inspect ${directory}`, { cause: error }));
  }
}
if (failures.length > 0) throw new AggregateError(failures, "Example failed");
```
