Revert #5642 because this generates:
```
// GENERATED CODE! DO NOT MODIFY BY HAND!
// This file was generated by [ts-rs](https://github.com/Aleph-Alpha/ts-rs). Do not edit this file manually.
export type GetAccountResponse = Account | null;
```
But `Account` is unknown.
The unique use of `#[ts(export)]` on `GetAccountResponse` is also
suspicious as are the changes to
`codex-rs/app-server-protocol/src/export.rs` since the existing system
has worked fine for quite some time.
Though a pure backout of #5642 puts things in a state where, as the PR
noted, the following does not work:
```
cargo run -p codex-app-server-protocol --bin export -- --out DIR
```
So in addition to the backout, this PR adds:
```rust
#[derive(Serialize, Deserialize, Debug, Clone, PartialEq, JsonSchema, TS)]
#[serde(rename_all = "camelCase")]
pub struct GetAccountResponse {
pub account: Account,
}
```
and changes `GetAccount.response` as follows:
```diff
- response: Option<Account>,
+ response: GetAccountResponse,
```
making it consistent with other types.
With this change, I verified that both of the following work:
```
just codex generate-ts --out /tmp/somewhere
cargo run -p codex-app-server-protocol --bin export -- --out /tmp/somewhere-else
```
The generated TypeScript is as follows:
```typescript
// GetAccountResponse.ts
import type { Account } from "./Account";
export type GetAccountResponse = { account: Account, };
```
and
```typescript
// Account.ts
import type { PlanType } from "./PlanType";
export type Account = { "type": "ApiKey", api_key: string, } | { "type": "chatgpt", email: string | null, plan_type: PlanType, };
```
Though while the inconsistency between `"type": "ApiKey"` and `"type":
"chatgpt"` is quite concerning, I'm not sure if that format is ever
written to disk in any case, but @owenlin0, I would recommend looking
into that.
Also, it appears that the types in `codex-rs/protocol/src/account.rs`
are used exclusively by the `app-server-protocol` crate, so perhaps they
should just be moved there?
